The Cometic fiber intake manifold gasket set for Chevrolet Mark‑IV Big Block V8 (.094 in) employs AFM material—nitrile synthetic rubber bonded to an aluminum core—giving heat and fluid resistance suitable for demanding flange conditions. AFM maintains strong torque retention and about 85% recovery, eliminating the need for sealants or re-torque. Built to meet or exceed OEM quality, it provides reliable sealing across varied surface finishes and load conditions.
