About this part

Product Details

When you're rebuilding the top end of your Gen-2 Hemi, getting the sealing right is critical. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of these powerful engines. It's designed to provide a strong seal between your cylinder head and block, ensuring proper compression and preventing coolant and oil leaks.

This gasket uses 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 conditions and various surface finishes. This construction means you don't need to use any extra sealants, and it works well whether you're pairing aluminum heads with an aluminum block or cast iron block. The center layer is stainless steel and can be varied to achieve different thicknesses, with this specific gasket set to a compressed operating thickness of .080 inches and a bore size of 4.280 inches.

This gasket is a solid option for a wide range of classic Dodge and Plymouth vehicles from the late 60s and early 70s, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger. It's a well-built component that helps ensure your engine rebuild is sealed up tight.
