I have a book by Tom Monroe, and I am pretty sure he says that you do not.
Tommorrow when I am in the garage I will try and remember to look at it and let you know for sure.
I run headers and use red high temp silicone with no gaskets and it works well for me.

1979MEANGREEN,
I just replace my 460 efi exhaust manifolds with headers (broken bolt, warped and cracked). When I took the manifolds off there were no gaskets installed by the factory. If your cylinder heads are smooth and clean around the exhaust ports, I would not use anything. This is how mine were and is running fine now.

There should never be a gasket between an exhaust manifold and head unless it is a steel shim gasket.
