Product Details
This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring a Viton rubber coating on the outer layers. This construction is designed to handle the demands of high-output engines and provides excellent sealing without needing additional sealants. The gasket has a compressed thickness of 0.030 inches and a bore size of 3.690 inches, specifically suited for the Jaguar 4.2L XK6 engine found in models like the XJ6.
The stainless steel layers offer increased strength and resistance to corrosion, while the Viton coating on both sides is heat-resistant up to 482 degrees Fahrenheit (250 C). This makes it suitable for sealing between aluminum heads and either aluminum or cast iron blocks, effectively managing the shearing forces that can occur. The center shim layer is uncoated stainless steel, allowing for variations in thickness to meet specific requirements.
This gasket is a solid option for rebuilding the top end of your Jaguar's engine. It's designed to fit right and perform reliably, ensuring a strong seal for your 4.2L XK6.
