I have found an outfit that sells .020 steel shims for head gaskets. It seems they are use a lot to correct valve geometry on OHV engines after the heads have been trued. They have them in stock for flatheads. A .020 shim will put me at .042-.051 squish, which is where I want to be. I have never used head gasket shims. Does anyone here have any experience with them? Any other feedback?
