About this part

Product Details

Cometic Gasket is known for making well-built sealing solutions for performance engines. This Multi-Layer Steel (MLS) head gasket is specifically made for Chrysler Gen-2 Hemi engines and features a 4.310-inch bore, with a compressed thickness of .030 inches. It's designed to handle the demands of high-output applications, ensuring a solid seal between your cylinder heads and engine block.

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 temperatures up to 482 degrees Fahrenheit. This coating is tough enough for various sealing environments and surface finishes, and it means you won't need any extra sealants for installation. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .030-inch spec on this particular gasket. MLS gaskets are also great for joining different block and head materials, like aluminum heads to cast iron blocks, as they can manage the shearing forces that arise.

This gasket fits a range of classic Mopar vehicles, including models like the Dodge Challenger, Dodge Charger, and Plymouth Barracuda from the late 60s and early 70s. It's a solid option for anyone rebuilding or working on the top end of these iconic engines.
