Which head gaskets? The common FelPro blue are 0.039” compressed I believe. Your calculator is also not taking into account gasket bore... small detail, probably not significant.

You are correct. I also read that I should have the Felpro "pre-crushed 1008 head gaskets for this head. I re did the calculations (added the head gasket CC's to the 58cc heads) using the Summit Racing calculator.
