Cometic AMC 390/401 Gen-3 V8 .080in MLS Cylinder Head Gasket - 4.250in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with embossed outer layers that utilize a Viton rubber coating, giving you a compressed operating thickness of .080 inches. These gaskets are designed for high-output engines and are ideal for sealing aluminum heads to either aluminum or cast iron blocks, handling the shearing forces that can occur between different metals. The multiple stainless steel layers offer increased strength and resistance to corrosion, while the Viton coating can handle temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments.

The center shim layer is uncoated stainless steel and can be varied to achieve different thickness requirements, like the .080 inch thickness on this particular gasket. Because they are made from multiple layers of stainless steel, these MLS gaskets have the ability to rebound and resist corrosion. They require no additional sealants, simplifying installation. This gasket fits a wide range of American Motors and Jeep vehicles from the late 1950s through the early 1990s, including models like the Jeep CJ series and AMC Ambassador.
