The Fel‑Pro performance intake manifold gasket set is designed without a metal core to let engine builders trim gaskets for exact port fit on modified engines. It’s been tested with many aftermarket cylinder head and intake combinations and supports both cast iron and aluminum cylinder heads. Intended for performance use rather than emission‑controlled vehicles, it helps ensure consistent sealing in custom applications.
