About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built for Chrysler Gen-2 Hemi engines with a 4.500 inch bore. You get one head gasket in this package, designed to provide a strong seal between your cylinder head and engine block. It's a well-built component for those looking to rebuild or upgrade their engine's top end.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction means the gasket can handle the demands of high-output engines and works well with both aluminum and cast iron blocks, even when paired with aluminum heads. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.

This gasket fits a range of classic Dodge and Plymouth vehicles from the late 60s and early 70s, including models like the Dodge Challenger, Dodge Charger, and Plymouth Barracuda. It's a solid option for restoring or enhancing the performance of these iconic engines.
