Head gasket question.
Im going to be swapping my stock rockers for Promag's. Im going to pull the heads off when I put the new springs on Comp918's. Anyway, Ive been thinking of going to a slightly thinner head gasket to bump the compression. Will this cause PTV issues on a stock cam, with 1.6 rockers? Im looking into an Impala gasket or something close to it. Any susggestions?

Unless you have a blown head gasket or are in need of a valve job badly, I would leave the heads right where they are and just do the spring swap in car and install the rr's. You can only expect like a 2% overall gain with the thinner Impala head gaskets. Not worth the effort if you ask me unless you are having your heads ported...

The Crane tool I bought long ago has holes for cap screws taht will screw into LS1 heads. The LT1 studs are not only larger in diameter, but the spacing is slightly different, so the tool I have wouldn't work on LT1's. so I had my machinist friend open up the holes and widen them to the center a little so that I can use them on LS1 heads and LT1 heads. They make a Crane spring tool for LT1's and one for LS1's...now I have one that works on both.
