Don't forget about the head gasket thickness and rocking the piston in the bores to get the minimum piston to head clearances
I'm going to use .055 P to V and P to head clearances on my KB aluminum wedge block pump gas build (572C.I.) with B1 heads
I'm shooting for right at 11.0 to 1 compression ratio and hoping to make near 1.5 HP per C.I. with one four barrel 1050 CFM Dominator gas carb using Oregon 92 octane non ethanol pump swill
