Cometic Chevrolet Mark-IV Big Block V8 .032in MLS Cylinder Head Gasket - 4.375in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with embossed outer layers coated in Viton, a heat-resistant rubber material. It has a compressed operating thickness of .032 inches and is designed for a 4.375-inch bore, making it a solid choice for Chevrolet Mark IV Big Block V8 engines. MLS gaskets are ideal for sealing aluminum heads to either aluminum or cast iron blocks, as they can handle the shearing forces that arise from the different materials. The multiple stainless steel layers provide increased strength and the ability to rebound, while also resisting corrosion.

The Viton coating on the outer layers is designed to withstand harsh sealing environments and varying load conditions, meeting the demands of high-output engines. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the .032-inch compressed thickness found here. These gaskets don't require any additional sealants, simplifying installation. This gasket fits a wide range of Chevrolet vehicles from the mid-60s through the early 80s, including models like the Impala, Chevelle, and C10 Pickup.
