I have an issue with getting a good seal between the exhaust manifold & head on the right hand bank of my v8. I have a continuous slight blow. The manifold has been removed and refaced & refitted with the standard metal gaskets. is their a better type gasket i can fit? Also i cannot use exhaust paste as the next joint on the exhaust contains the Cat.

Maybe stack up a few exhaust gaskets?

Plenty of composite manifold gasket types available as well as the tin ones. Just ebay search and dozens come up.

Have you checked the manifold face with a straight edge to see if it is even remotely flat?
You may need to have it machined or file it to a reasonable tolerance!

Yes Ian the manifold has been sent to a machine shop & has had the faces machined perfectly flat.

At least some SD1 V8 weren't fitted with any gaskets at all between head and manifold.
