Product Details
When you're rebuilding the top end of your 1973-1992 Jaguar XJ6 with the 4.2L XK6 engine, a reliable cylinder head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is designed to handle the demands of modern engines, offering a strong seal without needing any extra sealants.
Cometic builds these gaskets with multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This makes them suitable for sealing aluminum heads to either aluminum or cast iron blocks, as they can manage the different expansion rates between these metals. The center layer is stainless steel, and its thickness can be varied to achieve the specific compressed thickness of 0.051 inches with a 3.690-inch bore, ensuring a precise fit for your engine.
