Product Details
What you get here is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chrysler LA V8 engines with a 4.125-inch bore. This gasket has a compressed thickness of .140 inches, which is a common choice when rebuilding or modifying these engines. It’s built with multiple layers of stainless steel, giving it strength to handle high-output applications and resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that helps create a solid seal against aluminum or cast iron blocks without needing extra sealants.
These gaskets are a popular choice for engines that are pushed a bit harder, whether it's for street performance or racing. The multi-layer steel construction is strong and can rebound, helping to maintain a good seal even with the stresses of high compression or temperature. The Viton coating is tough and can handle harsh sealing environments, making sure your engine stays sealed up tight.
This gasket fits a wide range of vehicles, including classic Mopar muscle cars like the Dodge Charger and Challenger, as well as trucks and vans from the 70s and 80s. It’s a well-built component that’s ready to go to work in your LA V8 build.
