Cometic Jaguar 3.4L XK6 .060in MLS Cylinder Head Gasket - 85mm Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed for Jaguar 3.4L XK6 engines with an 85mm bore, and this particular gasket is 0.060 inches thick, which is an undersize specification. MLS gaskets are a solid choice for high-output engines because they offer excellent sealing without needing any additional sealants. They work well whether you're mating aluminum heads to an aluminum block or to a cast iron block, as they can handle the different expansion rates between those materials.

The strength of this gasket comes from its multiple stainless steel layers, which also help it resist corrosion and rebound effectively. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This makes it suitable for demanding sealing environments and various surface finishes. The center layer is uncoated stainless steel, and Cometic uses these layers to achieve precise thickness requirements like the 0.060 inches found here.

This gasket fits a range of classic Jaguar models, including the 1964-1968 Jaguar 3.4, the 1951-1957 Jaguar Mark VII, and the 1949-1953 Jaguar XK120. It's a well-made component that offers reliable sealing for your engine rebuild.
