Help me find a few parts?

I had the same problem with my b1 pipe and the way I fixed it was to cut an old exhaust gasket pull some the lead out(the gasket is made of wrapped layers of steel and lead) and wrapped the lead around the manifold before sliding the pipe on to it. That worked awesome for me.
 
Im gonna have to do that. The RTV did NOT hold. I used the Permatex Ultra Copper stuff. It held for a bit, but I can see where its just burned up and going to continue to burn up.

Im gonna have to use some sort of a metallic gasket, or just simply have the stupid thing welded.
 
when i got my engine built the builder used cometic EST gaskets and in the set was a metal gasket similar to a car header gasket, works great for sealing up the exhaust.
