Cometic Jaguar 1964-1968 4.2L XK6 .040in MLS Cylinder Head Gasket - 93mm Bore

If you're working on the 4.2L XK6 engine in your 1964-1966 Jaguar Mark X or 1967-1968 Jaguar 420, this Multi-Layer Steel (MLS) cylinder head gasket from Cometic is built to seal your engine's combustion chambers. It's specifically made to fit a 93mm bore and is .040 inches oversize, which is important if your engine has been previously machined or rebuilt to that specification.

Cometic uses a Multi-Layer Steel construction, which is a well-built choice for sealing the cylinder head to the engine block. This design offers improved sealing performance compared to older composite gaskets, especially under the high pressures and temperatures found in an engine. The gasket is designed to fit right, ensuring a reliable seal that helps maintain proper compression and prevent coolant or oil leaks between the head and block.

When rebuilding or repairing your XK6 engine, using the correct gasket size is crucial. This .040 inch oversize gasket is a direct replacement for specific Jaguar models and engine configurations, helping you get your classic Jaguar back on the road with confidence.
