I ended up using the Copper RTV instead... For what its worth, I found that Sanderson Headers recommend using ONLY red hi-temp RTV for their header gaskets, and it doesn't get much hotter than right at the exhaust port... I used the Copper because it says its good for an extra 50 degrees over the Red. I went back to the parts store and got another one of the gaskets I got yesterday, and used a layer of silicone between them. Now i just have to wait til tomorrow for it to cure, and see what happens.

The gaskets I got are for, among other applications, the late 60s Jeep V6.... I thought that was very interesting, especially because the bolt holes lined up so no trimming was necessary. Go figure...
