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 a solid option for sealing your cylinder heads. It's designed with a 4.310-inch bore and a compressed thickness of 0.062 inches, making it suitable for a range of classic Mopar applications like the Dodge Challenger, Charger, and Plymouth Barracuda from the late 60s and early 70s.

Cometic builds these gaskets using multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, meaning you won't need any extra sealants. This construction is ideal whether you're mating aluminum heads to an aluminum block or aluminum heads to a cast iron block, as it can manage the shearing forces that can occur between different metals.
