Thank you all for the great advice. I'll check out the Lunati cams and send back the ProComp heads immediately.

In the meantime, I'll confirm the cylinder volume, deck clearance and piston displacement. Then I'll do a "what if" analysis of the compression ratio (CR) with a number of head gasket and combustion chamber size options. Sound right?

What I'm discovering is that I should probably be shooting for a static CR of somewhere in the 8 to 9:1. Do you guys agree?

Also, I will definitely pick a head with below 190cc runners! I'm looking at the Edelbrock E-Street 5073 heads. 185cc runners / 70cc combustion chamber. Sound better?

Thanks again!
