I am almost ready to bolt my heads on. My pistons -5cc 2 valve relief are
.013 in the hole. With GM .028 gasket compression will be 10.2 felpro .015 will be 10.5 heads are 72cc chambers. Which gasket will get optimum quench?I guess you always need to check but with a 224/230 480/504 cam should I have any v/p clearence problems.Short block is a eagle 383 rotating kit if it matters. Heads are Dart pro1 platinums with 2.02 intake valves.

O.K after some searching and reading looks like the GM .028 gasket will give a .041 quench which should close to the desired .040.So how about the v/p clearence issue.Is my cam big enough for concern?

.015" will not be think enough IMO if your pistons sits only .013" in the hole.

I wouldnt never go under .030" quench. The risk aint worth the gain. The pistons rocks on the rods, higher RPM tends to let things flex more, etc. With that tight of a quench you could end up smacking a piston into the head/valves

I myself always shoot for .035" to .042" quench.

So to answer your question. If the pistons are .013" in the bore then I would use the .028" gaskets

It's always best to check V 2 P clearance. Too many things will change the clearance you have for any person other than builder of that engine to say for sure.

Now take it for what it's worth but on my 355 my specs are.
4.030" bore x 3.48" stroke
pistons in bore .025"
4.100" x .015" head gaskets

272/284*, 216/228* @ .050", .454"/.480" lift, 112 LSA cam with 1.6 rockers which brings lift up to .484"/.512" and adds a couple degrees duration to the .050" #'s so probbly about 220*/230*.

Great V 2 P clearance, No prob what so ever

O.K was playing around with the dynamic compression calc and looks like static will be 10.13 and dynamic will be 8.43. So far everything is going together right.Can't wait to fire it. The funny thing is that in the dyno 2000 program the next size up cam only made 2 more peak hp and less torque across the board. I was expecting the hp/tq curve to move higher up but thought the gains would be bigger.Even plyed with a bunch of comp cams magnum and XE line.The lunati 60103 won out. 400+ tq from 2K to 5500 with a 2400ish stall should be a mean street machine.
