Cometic GM Gen-V/VI Big Block V8 .040in. MLS Cylinder Head Gasket, 4.510in. Bore

This listing is for one Cometic Multi-Layer Steel (MLS) cylinder head gasket, specifically sized for GM Gen-V/VI Big Block V8 engines. It features a 4.510-inch bore and is .040 inches thick, designed to provide a reliable seal between your engine block and cylinder heads. This gasket is a popular choice for rebuilds and repairs on a range of Chevrolet and GMC trucks and vans from the early to mid-1990s, including models like the Chevrolet C1500 and GMC C2500 Suburban.

The construction uses multiple layers of steel for strength and durability, a common feature in modern head gaskets to handle the pressures and temperatures within these large displacement V8s. The outer layers of this gasket are embossed and coated with Viton, a high-performance fluoroelastomer known for its resistance to heat and oil. This coating helps the gasket conform to the sealing surfaces, ensuring a tight seal and preventing leaks even under demanding conditions.
