well my setup is a b18c1 ill be puting in brian crower stafe 3 na cams and i have b16b pistons i was planning on going e85 but now im not so i need to lower the compression to 12:1 from its 13:1 they would put me at ( and i didnt reserch them good enough before i bought em) but ill be using them
so i was thinking like a .045 head gasket acording to that calculator it would put me like right at were id like to be any imput on if that calculator is right?
