for my 3.8sc block build-up for my 93 I'm going to o-ring the block. I havent read much into it yet, but I am getting there. From everything I have seen so far people use copper head gaskets with this method so the metal ring will press into the soft gasket and make a tighter seal than a fire ring does. So I need copper gaskets correct? Where can I get my hands on some and is any particular brand preferred over any other (if there are multiple companies producing them) I'd assume Fel-Pro probably makes a set but I am unaware of it if they do.
