About this part

Product Details

Cometic Gasket is well-known for making robust sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a Chrysler LA V8 engine, this gasket is built to handle the demands of high-output applications. It's designed to provide maximum sealing performance without needing additional sealants, making it a solid choice for both aluminum and cast iron block combinations.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel and can be varied to achieve different thicknesses; in this case, it's set to provide a compressed operating thickness of .089 inches with a 4.125-inch bore. This specific design is well-suited for engines like those found in a Dodge Charger or Chrysler Cordoba, offering reliable sealing.

This gasket fits a wide range of vehicles, making it a versatile option for many classic Mopar builds. Ensure you have the correct bore size and thickness for your specific engine build.
