Rough idea for people who are deciding on new head gasket and wonder about comp ratio(unskimmed head&block), Stock comp ratio is 8.3:1
Stock head gasket 1.1mm
Stock head is 136.9mm - 137.1mm
Stock block is 211.25mm - 211.35mm
88.0mm Gasket 86.0mm Piston 87.0mm Piston
0.6mm____________9.2:1___________9.0:1
1.0mm____________8.9:1___________8.7:1
1.2mm____________8.7:1___________8.6:1
1.5mm____________8.5:1___________8.4:1
1.8mm____________8.3:1___________8.2:1

Not sure about the original head gaskets thickness Question Some how makes me wonder how come if you change original 1.1mm head gasket to multilayer 1.2mm then how comp goes up ???
