Cometic AMC 4.0L Inline 6 .056in MLS Cylinder Head Gasket - 4.000in Bore

When you're rebuilding the top end of your AMC 4.0L inline 6, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of your Jeep Cherokee, Comanche, Grand Cherokee, Wagoneer, or Wrangler. It's designed for a 4.000-inch bore and has a compressed thickness of .056 inches, making it a direct replacement for your original gasket.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction means the gasket seals effectively without needing any additional sealants, and it's suitable for use with aluminum heads on either aluminum or cast iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses, ensuring a precise fit for your engine.
