Hey everyone. I really need some advice from some experts. I'm currently building a 355 sbc. I planned on using flat top pistons with four valve relief with stock 76 cc heads but found out they were cracked and no good. So I recenlty bought some vortex heads 062 64 cc chambers. Now I'm afraid my compression ratio might be way too high. I'm assuming I have a deck height of .025( have not measured yet), head gasket thickness of .015 to give me .040 quench. The piston head volume is +6.00 cc, 4.030 bore, and standard stroke. My compression is coming out to be too high on pump gas. Any advice would be greatly appreciated. Not tryna build a race motor. Just a good power house for my c10. Please help!!!
