Cometic AMC 290/304/343/360 Gen-2/3 V8 .051in MLS Cylinder Head Gasket - 4.140in Bore

If you're rebuilding the top end of your AMC V8 engine, a reliable cylinder head gasket is crucial for sealing combustion, coolant, and oil passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines, offering a robust seal that helps prevent leaks and maintain proper engine function. It's designed to fit a range of AMC and Jeep vehicles from the late 60s through the early 90s, including models like the Jeep Wagoneer and American Motors Matador.

This gasket is constructed with multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion and maintain its seal over time. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, making it suitable for both aluminum and cast iron blocks. With a compressed operating thickness of 0.051 inches and a bore size of 4.140 inches, it's engineered to provide a precise fit for the specified AMC V8 displacements.

Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process. This makes it a solid option whether you're working on a stock rebuild or a more performance-oriented build.
