Cometic AMC 290/304/343/360 Gen-2/3 V8 .040in MLS Cylinder Head Gasket - 4.140in Bore

Starting with a compressed operating thickness of 0.040 inches, this Multi-Layer Steel (MLS) head gasket from Cometic is built for serious sealing. It's constructed with multiple layers of stainless steel, which gives it strength and helps 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 degrees Fahrenheit, making it ideal for high-output engines and various sealing environments.

MLS gaskets are a solid choice for both aluminum-to-aluminum and aluminum-to-cast iron engine blocks because they can handle the shearing forces that can occur between different metals. This particular gasket has a 4.140-inch bore and is designed to fit a range of AMC and Jeep V8 engines from the late 60s through the early 90s, including models like the Jeep Cherokee, Jeep Wagoneer, and American Motors Matador. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation.
