Re: Should I Run Exhaust Manifold Gaskets?

If you use those felpro or other gasket kit gaskets, they will blow, its only a matter of time.

Now if you are talking about a straight 6, they yes, there was a gasket.

Just my 2 cents, dont shoot my if you disagree.
I won’t shoot you. I agree. I’ve been waiting for someone to say it

I’ve never run gaskets with ram horn manifolds, other than a solid steel donut between the head pipe. Make sure all surfaces are flat. I’ve never had any leaks. I just make sure everything is right periodically.
