About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chrysler LA V8 engines. It features a 4.125-inch bore and a compressed thickness of 0.045 inches, making it suitable for specific engine builds, including those using World Products Man-o-War blocks and 318 A heads. This gasket is built to handle the demands of high-output engines and is a popular choice for rebuilding or upgrading a wide range of classic Dodge and Chrysler vehicles, such as the Dodge D150 Pickup, Dodge Charger, and Chrysler Newport.

Cometic constructs these MLS gaskets from multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This design means the gasket seals effectively without needing additional sealants, and it's well-suited for applications combining aluminum heads with cast iron blocks, as it can manage the shearing forces that arise between different metals.
