About this part

Product Details

Starting with a .045 inch compressed thickness and utilizing multiple layers of stainless steel, this Cometic Multi-Layer Steel (MLS) head gasket is built for the demands of high-output Chrysler LA V8 engines. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it ideal for sealing aluminum heads to cast iron blocks or vice-versa. This gasket is designed to provide maximum sealing performance without the need for additional sealants.

The multi-layer steel construction offers increased strength and the ability to rebound, helping to resist corrosion and withstand the shearing forces that can occur between different block and head materials. The center shim layer is uncoated stainless steel and can be varied to achieve different thickness requirements, allowing for precise tuning. This gasket is a solid option for engines with a 4.040 inch bore, specifically designed for applications using the 318 A head.

This gasket fits a wide range of vehicles, including models like the Dodge Charger, Chrysler Cordoba, and Dodge D150. Always refer to the manufacturer's installation instructions for proper fitment and torque specifications.
