Im looking for some pistons to throw in a B18C1. I cant seem to find ANY 9.5:1 / 81.5mm pistons. There sure is 9:1's!!! So... lets say i wanna use a thinner head gasket, how much will that change the compression. Im aiming for about 9.3-9.5. or vise versa, using a thicker gasket if i can find a 9.6-9.8 piston.
