Take it for what it's worth, but I use regular ole Permatex Ultra Black silicone for the headers. The Ultra Copper doesn't seem to stick to anything very well and that is why I stopped using it. I haven't bought header gaskets in 14 years, so I stay with what works.

does the silicon seal well? I would think that if the headers aren't perfectly flat that any area where there is thicker silicon would blow out?

How long do you wait for the silicon to dry before you can start the engine?

Old cheapy steel gaskets that came with the rebuild kit but I have a trick my buddy showed me. He owns a muffler shop and is a all Ford hot rodder and racer; he uses Tremcald roofing tar(insta-patch). I did the same trick and have re-used these gaskets 3 times and no leaks.
I've heard that the loc-tite cooper with no gasket also works well.
