Hi,
I am about to connect my new stock exhaust to the stock manifolds. They are both flat and I ws wonderingwhat is the best type of gasket to use to avoid leaks.
Thanks
Any stock type gasket should do if you are sure they are flat.
The stock manifolds seal much better then headers because they are made from the same material as the head. Cast Iron. In fact some would tell you you don't even need a gasket. I know a guy that just puts grease on.
