The Fel‑Pro performance intake manifold gasket set is built without a metal core so engine builders can trim the gasket for exact fits on modified ports. Printoseal elastomeric beads add sealing strength around intake ports. These gaskets have been tested with many aftermarket head and manifold combinations and are intended for race‑style use; they have no exhaust crossover openings or blocking shields.
