About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring a Viton rubber coating on the outer layers. This construction is designed to handle the high output demands of Chrysler Gen-2 Hemi engines, offering reliable sealing without the need for additional sealants. The Viton coating is heat resistant up to 482 F and is suited for various sealing environments, load conditions, and surface finishes, making it a solid option for both aluminum and cast iron block combinations.

With a compressed operating thickness of 0.036 inches and a 4.500-inch bore, this gasket is engineered to provide a strong seal. The multiple stainless steel layers not only increase strength but also allow the gasket to rebound and resist corrosion, which is crucial for longevity. The center shim layer is uncoated stainless steel and can be varied to meet different thickness requirements, ensuring a precise fit for your specific build. This gasket fits a range of classic Dodge and Plymouth vehicles from the late 60s and early 70s, including models like the Dodge Challenger, Dodge Charger, and Plymouth Barracuda.
