Cometic AFM oil pan gasket kit for Chevrolet Mark-IV Big Block V8, .075in thickness with trimmed side rails. The AFM material is a nitrile synthetic rubber bonded to aluminum, offering strong torque retention and chemical resilience. It resists temperatures above 205°F, recovers well after deformation, and is intended to seal the oil pan to the engine block without additional sealants or the need for re-torquing.
