The link shows a typical exhaust gasket with double sealing surface.

It seems fairly loose.....not sure how the setup is able to seal.. Those in the link however seem like they would be MUCH better. I wonder if I could get those to work on the revo.
I know there is an issue as I destroyed my 3.3 engine last week with this header. The connecting rod SPLIT right down the middle. I had to get another engine for it.
