Breathing new life into the 318 in the Scamp!

If these pistons sit .012 down, should I run a tighter head gasket than .039"?

I'm wondering if Something like an .028" would be more ideal? That would get me right in at .039 or a scratch over.

The .039"s are getting me in at .051" quench.

I'm a little concerned about longivity of the .028" Mr.Gaskets, but I don't know if it's relevant.

Does anyone make a gasket somewhere inbetween .039" and .028"?
