The Cometic AFM valve cover gasket for early Ford EAO Cosworth YB engines (.060in) replaces common cork or paper seals with a race-inspired AFM construction. AFM is a chemically blown nitrile synthetic rubber bonded to an aluminum core, offering about 85% recovery, strong torque retention, and temperature resistance above 205°F. It does not require sealants or re-torquing and includes a steel torque-limiting frame for consistent clamping.
