What raises compression one full point, thirty thousandths mill? Will I have any valve clearance problems on a B16 with stock pistons and some high-lift cams? Also, anyone know the compression numbers for skunk2 valves? They raise compression due to their flat-bottom valve design, but does anyone know by how much? Thanks in advance....

 

Anyone?

 

I don't know much but 30 thousands is alot. 20 thousand is safe. If you plan to mill the head and use high lift cams be sure to do the clay test to check valve clearence. Also, you should find out what the max cam gear setting you can use when doing the clay test too, since milling the head is irreversible, you should look in to a thinner head gasket or less layers. Using thinner head gaskets can bump you up a half a point.
