Cometic Chrysler LA V8 .120in MLS Cylinder Head Gasket - 4.080in Bore - With 318 A Head

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example of their work for high-output engines. This particular gasket, part number C5917-120, is built for Chrysler LA V8 engines with a 4.080-inch bore and is designed to work with 318 A heads. It's a well-built component that can handle the demands of performance applications.

What makes this gasket stand out is its construction. It's made 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 temperatures up to 482°F (250°C). This advanced coating ensures a reliable seal even in harsh conditions and works well with both aluminum and cast iron blocks and heads, preventing issues from material expansion differences. The compressed thickness is 0.036 inches, and the center layer is stainless steel, allowing for thickness variations to meet different needs.

This gasket fits a wide range of vehicles, including models like the 1970-1974 Dodge Challenger, 1975-1980 Dodge Aspen, and 1971-1981 Chrysler Newport. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward. It's a solid option for anyone rebuilding or upgrading their LA V8 engine.
