Need opinion

With the general description of the pistons, I ran CR numbers on your setup and come up with about 0.2 increase in CR for .020" extra. (Roughly 7.6 to 7.8 CR.) Not a lot. But if you go from standard Felpro head gaksets that are .051" think to MP thin head gaskets that are .028" thick AND add that .020 cut, then you are up to 8.25 CR, roughly a 0.6 points CR increase. You will feel that as a happy improvement in low end torque.
