Product Details
If you're rebuilding the top end of your classic Jaguar XK120, getting the cylinder head gasket right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and block.
Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and varying surface finishes, meaning you won't need additional sealants. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket is .040 inches thick with a 91mm bore, designed to fit specific Saab B204/B234 engines, and also verified for your Jaguar XK120, XK140, and XK150.
