So i hear that a 3mm will lower my compression one point, so thats from 9.6 down to 8.6...what would a 2mm gasket lower it too?

ok, so i found the compression calculator, and did it, the compression shoulod be about 8.7:1 if i converted the inch to mm conversion right, i put .080 for 2mm...is this correct, i belive it is. so this hsould be safe for 8 psi daily on stock internals with a dyno tuned V-AFC adn 370cc injectors and a front mount ( i think thats all the stuff that would count) am i corrrect?
