Cometic CFM-20 head gasket for Triumph TR3B/TR4/TR4A applications, .043-inch thickness with an 88 mm bore. The CFM construction uses a perforated galvanized steel core with asbestos-free fiber on both sides to provide even load distribution and reduced clamp requirements. This gasket is designed to minimize bore distortion and does not require sealants or re-torque under normal installation.
