 Do you or anyone else know if they are compatible?

I don't know. I make my own from thick wall tubing bends and the Racing Beat 
flanges. It is very easy to do, and there is a need for a very custom design 
anyway, not unlike an aircraft installation. I used some available tubing that 
had an ID of just under 2". The wall is close to .145". I don't know what it 
was but it worked out great.
I had made a set from .120" wall and then wrapped them with heat tape. They 
melted. So either use stainless for everything, or don't heat wrap the carbon 
steel headers. That heat wrap sure cools things down. So stainless is the 
answer.
