compression math
my head gasket is .045 compressed
how much needs to get shaved off the head for 10.8:1 compression?
For anyone to have a chance at helping you with the question you actually asked we would also need to know for sure what heads you are using rather than leaving us to asume LT1 aluminums????????
i need to have the heads decked from a knick or two and i rather have a thicker head gasket then a thin one plus i bought thje head gaskets 2 mts ago i doubt they will take returns
