Yep, I use that copper sealant too. Never had a problem.

Embossed metal head gaskets - are these also called steel shim head gaskets. Even though both surfaces were machined, you may have better luck with the thicker gaskets, which the aforementioned Ted Eaton suggests. And the ones from Best Gaskets which he also suggests..

Paul is correct; however, if your block hasn't been zero-decked, the added compressed thickness of the composite gaskets could put your quench beyond .060, which is not a good thing.
