About this part

Product Details

Starting with a compressed operating thickness of 0.040 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for Chrysler LA V8 engines. It's designed to handle the demands of high-output applications, whether you're pairing aluminum heads with an aluminum block or aluminum heads with a cast iron block. The multiple layers of stainless steel provide increased strength and resistance to corrosion, while the outer layers are coated on both sides with Viton, a heat-resistant rubber material rated up to 482°F.

This gasket doesn't require any additional sealants, making installation straightforward. The unique construction of MLS gaskets helps them withstand the shearing forces that can occur between different block and head materials. The center shim layer is uncoated stainless steel, allowing for variations in thickness to meet specific engine needs. This gasket is a solid option for a wide range of vehicles, including models like the Dodge D150, Chrysler Cordoba, and Bristol 410.
