Cometic Ford 351 Cleveland 4.100 inch Bore .045 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring Viton rubber coating on the outer layers. This construction is designed to handle the demands of high-output engines without needing additional sealants. The Viton coating is heat resistant up to 482 degrees Fahrenheit, making it suitable for harsh sealing environments and various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This gasket is well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as it can withstand the shearing forces that can occur between different metals.

The multi-layer stainless steel design provides increased strength and resistance to corrosion, while also allowing the gasket to rebound effectively. With a compressed operating thickness of 0.045 inches and a bore size of 4.100 inches, this gasket is engineered for a precise fit on Ford 351 Cleveland engines. It fits a wide range of Ford, Mercury, and De Tomaso vehicles from the late 1960s through the mid-1980s, including models like the Ford F-250, Mercury Cougar, and De Tomaso Pantera.
