OK, working on the current project, and looking at the gasket options out there.

Who knows what the GM 6.0L gasket diameter is? They are usually a little larger than the factory bore, but what is the actual size?

Is Cometic the only place to get aftermarket head Gaskets? What are my options?

Felpro part # 1041 will work with up to 4.125 bore... It's what I use on my iron block without any problems.
