About this part

Product Details

When you're rebuilding a Chrysler Gen-2 Hemi, getting the sealing right is crucial, and this Cometic Multi-Layer Steel (MLS) head gasket is built for the job. You get one MLS head gasket with a 4.310-inch bore and a compressed thickness of 0.120 inches. This gasket is designed to handle the demands of high-output engines, meaning it seals tightly without needing any extra sealants, which is a big plus during assembly.

Cometic builds these gaskets with multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes, whether you're pairing aluminum heads with an aluminum block or cast iron. The stainless steel construction also helps them withstand the forces created when mating different metals, giving you a solid seal that can rebound and resist corrosion over time.

This gasket fits a range of classic Mopar V8 vehicles from the late 60s and early 70s, including models like the Dodge Challenger, Plymouth Barracuda, and Dodge Charger. It's a well-built component that's essential for ensuring your engine runs smoothly and reliably.
