The Cometic fiber intake manifold gasket set for Chevrolet Mark‑IV Big Block V8 (.047 in) fits Brodix Race‑Rite 26° and similar heads and uses AFM construction—nitrile synthetic rubber bonded to an aluminum core—for heat and fluid resistance. AFM delivers strong torque retention, high recovery, and removes the need for additional sealants or re-torque. The gasket is manufactured to provide reliable sealing in varied flange and surface conditions.
