Cometic AMC 390/401 Gen-3 V8 .075in MLS Cyl Head Gasket-4.380in Bore-With Indy Heads-18 Bolt Head

This Cometic Multi-Layer Steel (MLS) head gasket starts with a compressed operating thickness of 0.036 inches, designed for AMC 390/401 Gen-3 V8 engines with a 4.380-inch bore and Indy heads. It's built with multiple embossed layers of stainless steel, giving it increased strength and the ability to rebound while resisting corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle demanding sealing environments and surface finishes, making it suitable for both aluminum and cast iron blocks.

MLS gaskets are ideal for high-output engines because they provide maximum sealing performance without needing additional sealants. The center shim layer is stainless steel and can be varied to achieve different thickness requirements, like the 0.075-inch thickness of this particular gasket. This well-built gasket fits a range of vehicles, including models like the American Motors Matador, Jeep Cherokee, and Jeep Wagoneer from the 1970s.
