Cometic Jaguar 3.8L XK6 .030in MLS Cylinder Head Gasket - 89mm Bore

When you're rebuilding the top end of your 3.8L XK6 engine, getting the cylinder head gasket seated correctly is crucial for a leak-free seal. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of high-output engines, offering a robust solution for your Jaguar or Ford project. It’s designed to work with both aluminum and cast iron blocks, providing a solid barrier against combustion pressure and coolant leaks.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating ensures a reliable seal even under challenging conditions and across various surface finishes. The center layer is uncoated stainless steel, and the overall compressed thickness is 0.036 inches, with this specific gasket being 0.030 inches undersize for your bore, and featuring an 89mm bore diameter.

This Cometic MLS head gasket fits a range of vehicles, including many Ford models from the 1970s and early 80s, like the Ford F-100 and LTD, as well as classic Jaguar XK150 and Mark X models. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process.
