Cometic Chevrolet Mark-IV Big Block V8 .056in MLS Cylinder Head Gasket - 4.375in Bore

When you're rebuilding the top end of your Chevrolet Mark-IV Big Block V8, getting the head gasket right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F and works well with different block and head materials, including aluminum to aluminum or aluminum to cast iron. The compressed thickness is .056 inches, and it's designed for a 4.375-inch bore, making it suitable for a range of Chevrolet Mark-IV Big Block V8 applications.

Because it's an MLS gasket with Viton coating, you won't need to use any additional sealants, simplifying the installation process. This gasket fits a wide variety of Chevrolet vehicles from the mid-60s through the early 80s, including models like the Impala, Chevelle, and C10 Pickup.
