Before I bought my Camaro from my friend, he installed Clifford headers, & an Offy intake manifold.
The Felpro gasket was on the car then with no leaks.
When I switched around intake manifolds I always used Felpro gaskets with the same Clifford headers, no leaks.
We did remove the alignment dowels & used bolts for the headers on the ends of the cyl head.
