Cometic Chrysler Gen-2 Hemi .051in MLS Cylinder Head Gasket - 4.500in Bore

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chrysler Gen-2 Hemi engines with a 4.500-inch bore. It's built to handle the demands of high-output applications, providing a solid seal between your cylinder head and engine block. These gaskets are a popular choice when rebuilding or upgrading engines like those found in classic Mopar muscle cars, offering improved sealing over older gasket designs.

Cometic constructs 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 high temperatures up to 482°F (250°C) and works well with different surface finishes on aluminum or cast iron blocks. The center layer is stainless steel and can be varied in thickness; this particular gasket has a compressed operating thickness of 0.051 inches, which is important for maintaining proper compression ratios. Because they are MLS, these gaskets don't require any additional sealants, making installation more straightforward.

This gasket fits a range of classic Chrysler V8 applications, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s. Ensure you check the full fitment list to confirm compatibility with your specific vehicle.
