The Cometic .039-inch fiber intake manifold gasket set for Ford FE V8 engines uses AFM material—a chemically blown nitrile synthetic rubber bonded to an aluminum core—rated above 250°F with about 85% recovery and strong torque retention. Sized for FE rectangle ports (1.408" x 2.345") and excluding 427 SOHC applications as noted, these gaskets offer excellent sealability, OEM-quality manufacturing and do not require sealers or re-torque.
