The Cometic CFM-20 head gasket for Jaguar 1964–1968 4.2L XK6 is a 93mm bore, .043-inch gasket featuring a perforated galvanized steel core with asbestos-free fiber material bonded to both faces. The CFM design evens load distribution across the sealing area, creates less bore distortion, and is intended to require less clamp load; Cometic notes no additional sealants or re-torque are required.
