Cometic Chevrolet Mark-IV Big Block V8 .080in MLS Cylinder 4.320in Bore Head Gasket

If you're rebuilding the top end of your Chevrolet Mark-IV Big Block V8, getting the right head gasket is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) gasket is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and block without needing extra sealants.

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. The compressed thickness is .080 inches, and it's designed for a 4.320-inch bore, making it suitable for a wide range of Chevrolet Mark-IV Big Block V8 applications from the 1960s through the 1990s, including popular models like the Impala, Chevelle, and C10 Pickup.
