i had mine flow tested.. stock procomp 195cc 64cc chamber heads.. 3001 is the part number on them i think...

for what they are.. they seem to flow pretty well...

That part number is the "Chinese" heads we tested on the dyno a few months ago. Supposedly they are "Made in Australia". In reality only the "paper-trail" goes back to Australia, the castings are definitely from China. We had been approched by a local warehouse which was considering taking on the line. They did so after we passed them the test results and they "upped" the HP claims in their ads. They initially were going to read as being able to deliver 420 HP "from the box", that number went to 450 HP.

Now having said that, these SB heads actually do work reasonably well for what they cost. They will support 450 HP on our "pump-gas" 383 basic strokers without any aggressive porting, only very slight "massaging", we would actually say "just cleaning up the runners". The ones we tested had the identical part number (PC-3001) and as I stated, performed well. They were delivered to us with the 2.020"/1.600" valves and springs for the test.

The CFM for the intake valve was 260 (average) at .600" lift and the exhaust was 170 @ .600". These numbers are from both our flow benches not from the ads. Not all that bad for "inexpensive" Chinese aluminum heads.

These heads can actually be brought up to "excellent" flow numbers by almost anyone familiar with some "basic" porting procedures. We have a unit at the door, waiting to be picked up, a 383 SB with these #3001 heads on top that made 440 HP and 450 Ft.Lbs. torque. This was a non-ported set.
Thanks, Gary in N.Y.

P.S. They've since cast up the BB's but we haven't been asked yet to get involved. We saw some of the (first-batch) original BB blanks a while back and recommended the warehouse to "pass" at that time. I believe they've made some corrections from the first ones we checked out, but we don't know this for sure.

I'm new to the board. I'm building a 350. I just purchased a set of heads from PBM. Their part# is C1982363A for angle plugs. Guess what? Part# engraved on head is PC3001! Looks like these heads are getting around.

I think, (I think), Powerhouse and Hotrodsusa are selling the BB heads at a reasonable price??

As maybe Steve is at Texas Performance??

Guy's, I figure they are good value for your hard-earned buck.

NOT race heads but still good value, imho, right Gary...

I would advise seriously checking before buying. Over on hotrodders.com there was a very long thread about these very same heads and it even included a rep from the company I believe. Caveat emptor, 'let the buyer beware'. Don't ever say you weren't warned.

Mine seem to work excellent although I dont believe the quality is as good as my Dart heads. But, I was looking for a cheap aluminum head for a mild street stroker and they fit the bill well. Overall I am happy. If i were to do it again I would take a very hard look at the E-tecs though.

I dont blame you. I was sort of mislead when I bought these heads. I was initially told they were from RHS over a year ago when I bought them. I realized something was up when I started to try to find info on them. I phoned RHS and asked them. Of course they said "Those arent our heads". WTF!!! I had a hard time getting info on them and when I phoned some other places about them they either did not or were reluctant to answer my questions. I was pissed. But in the end it all worked out well for me. BUT, it does still irk me that they arent manufactured in North America. It has bothered me so much that I am positive that when there is a little more cash flow I will sell them and try a different head. Like AFR or the eddy E -tec.

I bought my Brodix RR200's from tonybarkerracing engines.com. I know they are a bit more than those pro whatever heads, but they are the next best things to AFR's from what I have learned. The AFR's I wanted were going to end up costing me near $2000 after the machine work to mill them down to 64cc, adding the necessary spring setup, etc. These Brodix's, CNC'd, ready to bolt on, were just over $1400. I also picked up some Conteco head gaskets and port matching Fel Pro intake gaskets very cheap as well. You can check out their website, but give them a call. Tony is very good to talk to and very helpful.

I don't know how much you are willing to spend, but take a look at both Summit and Jegs. They have Brodix IK heads for $999. Those ProComp heads would not hold a candle to the quality of the Brodix - casting and component quality. JMHO

I know I've probably asked before, but do you figure these are the heads Hotrodsusa are selling?

Hey guys,
Does milling a head to lower the combustion chamber 'cc' also decrease flow? Thats what AFR said and what I've experienced when checking out Trick Flows line of heads. Their 64cc head flows 240-ish @ .400 where as their 62cc flows 230-ish. Having said that, I'm pretty happy with my 62cc Trick Flow. For 10:1, I'd have to use a .015 shim gasket with a 64cc head whic scares me too much, so basically I'd have to mill just about every head out there which in turn would lower the flow data on every head out there. So after milling, an AFR would be somewhere in the mid 230cfms @ .400...down from 243cfm... so would Brodix, Canfield, etc.... I have 230cfm @ .400 now without milling with the TFS heads..so thinking out loud here...I would assume if I'm going for 10:1CR then, I'd have to mill every other brand and the mid 230s is the best I'm going to get from basically any "out of the box" head. I guess I'm good to go then...

So decreasing flow when milling is just something to condsider when buying heads....in my case it had me shopping for another brand with a lower combustion chamber. Otherwise I *may* have checked out Brodix, Dart, AFR...if they made a 62cc or lower chamber that flowed 230s or more @ .400. But like I said, I'm happy so its neither here or there... Thanks for listening my boring rants...;)

I guess I don't know what's going on with Shawn's rant b/c I always assumed that if you angle-milled heads to drop the chamber volume that the valves were positioned better for a better shot at the cylinder which helped flow..

(23 vs 18 vs 15 vs 10 degree heads sorta deal is all here??)...

I do know that you have to do all the rest of the machining to make sure angle-milled heads fit correctly, but what's up with the flow dropping thing??

OR is this just for flat-milled heads???

Im only going with what the AFR guy told me... Its not my claim. I would like to think that ther customer service would know a thing or two... but thats not always the case. I think I'll give them a call again and see if I get the same answer.

So my previous rant still stands... When buying a head... your not getting the numbers that are advertised if you have to mill. That should effect peoples decisions when buying heads.... go for the correct combustion chamber right out of the box instead of making a mistake... like: "I got a set of barely used 72cc AFRs for $999!!! ...not realizing that the guy needs a 68cc head with the thinnest gasket to get the necessary CR to run his cam...$150-$200 for milling and now he has spent about the same amount of money as he would've if he had just bought the 68cc new. And his "barley used" milled heads don't flow as much as the the new ones either... Mistake..

I'd love to get a new set of BB heads. $790 is pretty cheap. $1290 w/valves, springs ect. I'm sure there will be a few hundred in machining and studs/guideplates so, lets say
Complete for $1500.

A pair of Brodix Racerite are $1900 at Summit.

$400 will buy the gaskets and new roller rockers.

Shawn, from what I understand, every AFR head starts out around 72 or 74 cc's. I believe they then have to be milled down to whatever particular size the purchaser wants. I was going to buy some AFR's through Lewis Engines, and Mike Lewis told me that.

I snagged a pair of the big block heads to check 'em out. Machine work isn't the best but a good head man can clean the chambers up nicely. They're a ProTopline knock-off and aren't the same quality for sure. Still, when you consider that old tech GM 990/188 heads are more expensive and cast iron, these can't be too bad as long as the seats don't fall out. I'm gonna have mine cleaned up and flowed within a couple of weeks, I'll post how they compare to other heads that have been flowed by my local performance shop.

So my previous rant still stands... When buying a head... your not getting the numbers that are advertised if you have to mill. ..

True and not true. Yes, if you just mindlessly make big cuts on any head, you 'can' screw up the design, chamber and flow. But it depends on the head if it's a big deal or not, or if it hurts or not. By the same token, like pdq said you angle mill and roll the valve angle over, a 'real' head guy can take advantage of the new valve angle, work the port, bowl and chamber to increase flow. I have a set of AllPro 245cc sbc heads that were angle milled to 43cc's, Bishcoff developed a port and chamber that complimented the other tweeks in the heads and made flow that knocks the socks off a lot of BBC heads, and is significantly more than the standard 23 AllPro 245 head. My AFR 210's were angle milled to 55cc, AFR did some cnc port work after everythig else was corrected, and they flowed just about what a set of 220's flow. So the statement that milling kills flow is not always exactly right.
