About this part

Product Details

If you're working on a Chrysler Gen-2 Hemi engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of high-output applications. It's designed with a 4.500-inch bore and a compressed thickness of 0.056 inches, making it suitable for a range of classic Mopar performance builds from the late 60s and early 70s, like the Dodge Charger or Plymouth Barracuda.

Cometic's MLS gaskets are well-built using multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that seals effectively against aluminum or cast iron blocks and heads, even under high stress. This construction helps prevent leaks and withstands the forces created when mating different metals, ensuring a solid seal without needing extra sealants.

The center layer is stainless steel and can be varied to achieve different thicknesses, allowing for precise tuning. This gasket is a solid option for rebuilding or modifying your Gen-2 Hemi for improved performance.
