About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chrysler Gen-2 Hemi engines. It features a 4.500-inch bore and a compressed thickness of 0.086 inches, making it a solid option for rebuilding or upgrading these classic Mopar powerplants. These gaskets are built to handle the demands of high-output engines and are suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations.

Cometic constructs these MLS gaskets from 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 temperatures up to 482 degrees Fahrenheit, ensuring a strong seal even in harsh conditions. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the 0.086 inches found in this gasket. Because they are made of multiple layers and use Viton coating, these gaskets do not require any additional sealants, simplifying installation.

This gasket fits a range of classic Chrysler vehicles, including models like the Dodge Challenger, Dodge Charger, and Plymouth Barracuda from the late 1960s and early 1970s. Ensure you verify fitment for your specific vehicle application.
