I have my engine out so changing a few gaskets and seals. I pulled the exhaust manifolds off and the gaskets (don't remember the brand) with 30,000 miles on them are pretty much shot. What is the best gasket to get that will last much longer?

Thanks.

 

None.

AFAIK the factory hasn't used gasket on exh manifolds since the late 60s. What you're experiencing is EXACTLY why.

Just clean up both surfaces, use a flat mill file on the manifold if it's real rough to get it as absolutely flat as possible, and bolt em up.

 

I have owned this car since new and so I know it did come from the factory with exhaust manifold gaskets originally. The surfaces are a bit rough and I can flat file them but still intend to go with gaskets. I just ordered some Mahle gaskets that appear to be better than the FelPro ones as near as I can tell and look closer to the original factory ones.
