What is the compressed thickness of this head gasket?

The compressed operating thickness for this Cometic Multi-Layer Steel (MLS) head gasket is .038 inches. This measurement is important for ensuring proper compression ratios and valve-to-piston clearance.

Does this gasket require any sealant during installation?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. The multi-layer steel construction with Viton coating creates a robust seal on its own.

What makes the Viton coating on the outer layers important?

The Viton coating on the outer layers is a heat-resistant rubber material that can withstand high temperatures, up to 482 degrees Fahrenheit. This is crucial for maintaining a reliable seal in demanding engine environments.

About this part

Product Details

What you get here is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chrysler Gen-2 Hemi engines. This gasket has a 4.500-inch bore and a compressed thickness of .038 inches. It’s built with multiple layers of stainless steel, with the outer layers coated in Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction is ideal for high-output engines and works well with both aluminum and cast iron blocks, helping to manage the stresses between different metals.

The multi-layer design gives these gaskets increased strength and resistance to corrosion, while the embossed outer layers with Viton coating ensure a solid seal even under demanding conditions. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .038 inches on this specific gasket. Because they are MLS, these gaskets don't require any additional sealants, making installation more straightforward. They are a solid option for rebuilding or upgrading engines in a wide range of classic Mopar vehicles, including models like the Dodge Challenger, Plymouth Barracuda, and Dodge Charger from the late 60s and early 70s.
