Product Details

Starting with a compressed operating thickness of 0.030 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for the demands of AMC 390 and 401 Gen-3 V8 engines. It's designed to provide maximum sealing performance, especially for high-output applications, and works well with both aluminum and cast iron blocks. You won't need any extra sealants with this gasket.

The strength of this gasket comes from its multiple layers of stainless steel, which also help it rebound and resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness adjustments. This well-built gasket is a solid option for rebuilding or maintaining a wide range of classic American Motors and Jeep vehicles.
