The Cometic .043" CFM-20 cylinder head gasket for Lotus Twin-Cam engines (85mm bore) is a precision gasket that uses embossed outer layers coated with Viton. Built from carefully selected materials to meet application demands, it conforms load distribution across the sealing area, reduces bore distortion, and is supplied to perform without additional sealants or re-torque in appropriate installations where CFM-20 dimensions match the engine.
