About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for specific applications, including the Jaguar 3.8L XK6 engine and certain Dodge HEMI engines like those found in the Challenger, Charger, and Magnum. It features an 89mm bore and a compressed operating thickness of 0.036 inches, making it suitable for high-output builds where a precise seal is critical.

Cometic's MLS gaskets are built with multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle demanding sealing environments and various surface finishes without needing additional sealants. The center layer is uncoated stainless steel, allowing for different thickness options to meet specific build requirements. This construction helps manage the shearing forces that can occur between aluminum heads and cast iron blocks, ensuring a reliable seal.

This gasket is a solid option for rebuilding or modifying engines where maximum sealing performance is a priority. It's designed to work with both aluminum and cast iron blocks, offering versatility for different engine configurations.
