About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with three layers of stainless steel, featuring embossed outer layers coated with Viton rubber. The compressed operating thickness is 0.036 inches, and it's designed for a 4.200-inch bore, making it a solid choice for high-output engines like the Ford Boss 302.

MLS gaskets are known for their strength and ability to rebound, which helps them resist corrosion and maintain a strong seal even with dissimilar block and head materials, like aluminum heads on cast iron blocks. The Viton coating on the outer layers can handle temperatures up to 482 degrees Fahrenheit, ensuring it holds up in demanding sealing environments. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .045 inches on this specific gasket.

These gaskets don't require any additional sealants, simplifying installation. They are well-suited for applications using World Products Man-o-War blocks and SVO heads.
