Can any tell me about the procomp heads man the pricing is good.What is the flow rate on them. Do they hold up. Is there any 1 comparing them to other heads. This guy on ebay selling them he said they do all the machine work on them before they leave the shop, They are bolt on ready to go, they will not have to be rework by another machine shop this what the guy Ron said, Any 1 out there bought from these guys.

"O" I'm new to the forum thanks

I tknik they are china heads but i wouldnt swear to it.

funny, greezer,The car is in the shop now for springs, the heads I'm using are 822 350/400 heads posted porlish shave down some. valves 202/160. But man
the price is good on the procomp heads. The guy Ron at the shop said he will give me a 1 year warranty on them, And at his shop 80% of the work they do is heads. You no of any 1 buying heads from them.

I have looked a a set.I don't know who built them.They had .100 longer valves and 1.43 springs but only about 90 to 100lbs of seat pressure.Shims would fix that tho.The exhaust ports had a big ridge in it were the seat had been cut.It would be easy to improve the exhaust.The valve geometry was good on number one but on some of the others the roller tips were not setting flat on the tips of the valves and others they were not centered over the valve.

First off It would help to know what they are going on.What is the engine size cam,bored out etc etc...These heads are a good buy for a budget minded build! If you have the money to spend then get good heads from one of the well know manufactures, but if you are strapped for $$$$ and need to do this on a budget then get them.These look alot like the Patriot freedom heads I got last year.Everyone hear told me to avoid them etc.. Well I took a chance & bought them & so far so good! When they arrived I showed my engine guy the heads and he was surprised with them.Told me they were a great deal for the $$$$ & I spent $700.00 for mine.
Not for nothing but most sellers on E-bay will tell yah that they specialize in heads & most sellers on there selling these as well as the patriots all claim to do the work in house bla bla bla...Just do some reserch before you comit to buy.I actually called Patriot before I bought mine threw one of there dealers on e-bay to get some info.They told me the casting were made in Alstrialia & machined and assembled in the USA...Not sure about the Pro-Comps but I'm sure the claims will be similar from other sellers on E-bay.I have been told point blank that the pro-comps were cast in china though.
It all depends on what your expetations are & the use of the car.If your a drag racer then go name brand.If this is a street car & ocasional track blaster & you looking to do this on a budget ??? Well then I say take a chance..!
I did & I'm very happy with my Patriots, especialy for what I paid!
Good luck

I think they flow horrible from what ive read, If the price of those heads is your budget look at RHS Vortecs from competition products. I read good things about Patriot heads I dont think there is any comparison. Patriots are made in Georgia or something?

Save your money.
All the Chinese heads should be avoided.
Yes its nice to buy something for 1/2 price.
Its 1/2 price is NOT from a collaboration of the Quality US head manufacturers raking in Mega-Trillions of dollars off of poor hot rodders.
Real quality costs money. You have to pay real machinists a living wage. Virgin Aluminum costs money that has all the proper heat treatments and testing costs money too.
Re-re-re-melted scrap aluminum that MAY be a mixture of who knows what with weak spots, porosity etc is far cheaper as is the near slave labor.
How good is the warranty when a port wall blows out at 6000 RPM near the top of 2nd gear and the cylinder fills with coolant and hydraulics the motor?
You get another head? Maybe.

AFR's are the cream as far as CNC ported aluminum heads.
AFR, Canfield, Brodix, Edelbrock, TFS, RHS are great heads that work, last, and have real benefits and quality. The AS Cast ports of the Canfields are SUPERB! You would swear they were ported then sandblasted in the ports.

Save your coins and spend the extra for some real good heads. Its better to buy real quality parts then looking at others' taillights.

Man... "hhott71" it's the same thing over & over with yah every time someone asks about these types of heads you bash them into the ground.You & a couple others on hear did the same thing to me when I asked about the Patriots....!
If the guy is trying to do this on a budget & that is what he can afford,then what is wrong with that? Not everyone can afford $1000.000 to $1400.00 for name brand heads & all the ones you mentioned except vortecs are in that range!!!
Not for nothing but my Patriots came just as you describe hear: (The AS Cast ports of the Canfields are SUPERB! You would swear they were ported then sandblasted in the ports). All my suraces were machined to perfection no burrs or seams on any of the sufaces smooth ports nice blended bowls,quality components etc etc...Becuase they were built in AMERICA and cast in Alstrailia... Not sure I can say the same for Pro-Comps but the overall casting look similar if not identical.It all depends what shop finishes them and assembles them as well as the components they use!
As far as Pro-Comp's are concerned???? I'm not 100% sure how they compare to Patriots or other budget heads on the market, but if he does his reserch & looks into the back round of the shop that is claiming to be building them in house,then he will know for sure.He may even look to see if others have purchased from them & sak them how the heads are.That is what I did...I was going to go the route of AFR's or Edelbrock RPM's But why spend $1000.00 to $1400.00 if you don't have too,that's money that can go toward the rest of the motor/cars needs!
If money was no object then yah maybe I would have gone name brand also.I took a chance & went with Patriot's and so far so good!
Unless you have first hand knowledge of these heads he's interested in as being junk or not worth the $$$ then I wouldn't be bashing them!

The 882 heads machine to 74cc chamber 2.02/1.60 valves 2.22 intake port cross sections 195cc intake ports with butter fly pistons. roller rockers 1.5/1.6 Schneider cam 780cfm carb 10 fly wheel 4 speed manual 373 gears.

All so have 84 chevy S10 with L98 350 40 tpi motor, a 84 mazda rx7 with 372 mopar motor with 727 trany and dana 60 rear.

The procomps, if can save some money to put some where els in the car would help. Trying pull off some pounds of the car and to remove a little heat.
If there some 1 that bought these heads now and used them from these guy shop that what I was asking - they guy saying he machines the heads when they come in so who ever buy's from him they are bolt on and go. He has very good feed back to. For these price you can 2 sets.

Well with the work done to your existing heads I don't see you getting much more performance from the pro-comp heads your interested in.They will get yah a little more compression & save you some weight & disipate the heat better but that is about it.Not sure if they will flow better either,they may but you would need to have them flow tested to be sure.For the price though you just can't beat them.I would do some reserch about that company,ask some of thier past customers what they thought.Go to his e-bay seller page look on his feedback rating look to see who else purchased the same heads & e-mail them threw e-bay & ask them what they think about the heads.I would try to get all the info you can & make an informed desicion.
I was in your same boat last year.I was going to spend the big $$$$ on heads but then read some stuff about patriot in the back of hot-rod mag. Then I saw them on E-bay & I asked arround hear.I got a lot of negative feedback from members hear about cheap chinies knock offs etc.I went & did my own reserch & went with my gut feelings & bought the Patriot's. I'm not the only one who was asking about them or bought the Patriots.As far as I know there are other members who bought them & they too are happy with them.I remember one even had his flow tested & the results weren't that far off what Patriot clams them to do! From what I've seen & read about the pro-comps it doesn't look like theye are much different then the Patriots.I've seen both in person & they look identical.Even spoke to people who had pro comps on thier cars & no one ever said they were junk.They just said they were a good alluminum head for the $$$!
Good luck with you desicion.

I will keep seaching and talking to poeple who may have bought them and go from there.

it's funny 327 motor if kicking 350 383s I have 1900 miles on it, I did 7 1/4 miles races and won them all, buick 455 stage 1, duster 360,ford maverick, chevelle 72 396, My L98 chevy S10 350 40 over motor 5 speed automatic 390 gearing. camaro 2nd gear walk away from it

The shop I use the most is in MD shop name Supercar Automotive, parts service dyno custom engines Donald Durham runs the shop now which was the and 1 only Malcolm Durham man this guy had some fast cars back in the 50s 60s and 70s.

After looking at them I felt they were one step above heads like you have.I would have that company build a set to your specs,spring press, better porting etc..

I flipped a coin bought a set of the aluminum procomp 190's for a recent low budget rebuild.....haven't fired anything up yet, so I'll reserve my opinion of them for later. I think they look OK...it kinda freaked me out when I opened the box and saw this....when I specifically ordered Aluminum...

but I flipped the box over and it had Alloy on it...same box for both materials....LOL

[quote=jag327] and to remove a little heat.
.


I think a motor at 175 with alum heads is the same as a motor at 175 with Iron heads, I dont buy the aluminum head motor runs cooler thing too much, maybe it will cool faster when shut off? IDK?

Man the people so far like the heads but have not install them yet.

Let me no please what you thank about them, how it the finish the springs seats, Do anything look out of line, what about in side the ports..

I have a set of procomps which I've been running for close to 18 months. They look exactly like the ones your looking at. I have a "LT4 hot cam with 1.6 rockers". The heads are set up for .600 lift. Mine were solD to me as PBM Strikeforce heads. I have had no problem with them. I do not race. If I did I probably would buy something else just for piece of mind.

The motor will run a little cool in side the combustion chamber with them...
can you email me some pics please all the way around the heads and inside the ports both sides if you can. to jagcompany@aol.com when you have time.
What company did you buy the heads from....

Mwilson nice set up, I check the heads out thanks and the car, what compression your running with the cam, 11./11.5

The ones I looked at were 210cc intake ports.Take an exhaust valve out and look at the port and see what the spring pressure is at their installed height.I wonder how consisten everything is from head to head

I order 2 set of the procomp 210cc, 1 set supercar automotive if buying. Donald the shop owner thought it was a good deal he will check them and flow rate them. I they need any work he will do it free for me.

you can check my car here I load some pics, I will load later on my Dads race car

Hey Jag, what part of MD are you from? I live up in Cumberland.I have all my machine work done by Rhodes Performance in Somerset PA.I've been going there since the mid 80's.A few years ago the owner, who's name is Ron,and his son Chris, went into seperate business's.Chris opened up another shop in Fairmont, and specializes in high end race engines.I wonder if the E-Bay seller is one of these two people? If they are you will have no worries as both of them are really great stand up guys! Thats why they are they only people I will let work on my stuff

Where you able to bring up the pictures

I'm interested to hear what you find out about these heads. I'm putting together a 427 BB and aluminum heads are on the menu, but I've been looking for used Edelbrock heads. If these really are good, that would be a good thing for a lot of people.

Supercar Automotive, Donald Durham runs the shop now. they go back to the late 50s, My Dad race his brother Malcolm back in late 60s mopar 440 back then. They been doing most of my work for years and there's another shop in clinton md if he gets back up. But like to stick with them. They put out some super motors. The work with me on the mazda RX7 84 mopar 372 power.
back in the late 70s they work 454 60 over chevelle, 65 impala 327 30 over had this heavy car hit low 11s. with rear 411, a buick 73 455 stage 1, 350 vega and few others.

Man the pricing has always been very good for me. I tell them where a like to go with a car and they put it there and with my 2 cents.

I did all so few races around summit point in VA with hop up celica gt.
In 86 89 use to race at summit with few yamaha fz750s and the 88 fzr1000
