ive got hks 87mm pistons and im looking for a headgasket to use but cant make myu mind up on whether to use a 1.2 or 2.0mm or maybe somthing in between? 1.4, 1.6 mm etc i plan on running between 1.8 and 2bar of boost. I`d prefer to go with the 1.2mm hg as ive heard u will gain more torque and also its feels better off boost but my main concern is det ? will it be ok to run 2bar on a 1.2mm hd?
