Cometic Chevrolet Mark-IV Big Block V8 .084in MLS Cylinder Head Gasket - 4.630in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring a compressed operating thickness of 0.084 inches and a 4.630-inch bore. It's designed to provide maximum sealing performance for today's high-output engines, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron head and block combinations. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal in demanding conditions.

The strength of these MLS gaskets comes from their layered stainless steel construction, which also allows them to rebound and resist corrosion. This design helps them withstand the shearing forces that can occur between different metal types, like aluminum heads and cast iron blocks. The center shim layer is uncoated stainless steel and can be varied to achieve different thickness requirements, offering flexibility for engine builds. Because they are designed for high performance, these gaskets do not require any additional sealants.

This gasket fits a wide range of Chevrolet vehicles, including models like the 1965-1975 Chevrolet Bel Air, 1965-1972 Chevrolet Biscayne, and 1973-1974 Chevrolet Blazer, among many others. It's a solid option when you need dependable sealing for your Mark-IV Big Block V8 engine.
