Cometic AMC 290/304/343/360 Gen-2/3 V8 .080in MLS Cylinder Head Gasket - 4.140in Bore

Starting with the embossed outer layers coated with Viton, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing. Viton is a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it ideal for the demanding environments found in high-output AMC V8 engines. This gasket is designed for a 4.140-inch bore and has a compressed thickness of 0.098 inches, with the center stainless steel layer adjustable for various thickness needs.

MLS gaskets are a smart choice for both aluminum-to-aluminum and aluminum-to-cast iron block setups. The multiple layers of stainless steel give these gaskets increased strength and the ability to rebound, helping them resist corrosion and withstand the shearing forces that can occur between different metals. Because they are designed for maximum sealing performance, these Cometic gaskets typically do not require any additional sealants, simplifying installation.

This gasket fits a wide range of AMC and Jeep vehicles from the late 1960s through the early 1990s, including models like the Jeep Cherokee, Jeep J10, and American Motors Matador. It's a well-built component for rebuilding or repairing the top end of these classic V8 engines.
