which head gasket?

i knew that we should have between .035-.045, the ideal quench area, but even my machinist was a little skeptical on the .039 gaskets even though we were never hitting before, which is why he wanted to go with the .060 gaskets. he didn't even think to look in his marine book, but after i told him about the suggested gasket he ordered it.

thanks monte, jack, for the suggestion of the gasket and your input.
