Cometic GM Gen-V/VI Big Block V8 .086in MLS Cylinder Head Gasket - 4.375in Bore

Starting with a .086 inch thickness and a 4.375 inch bore, this Cometic Multi-Layer Steel (MLS) head gasket is built for GM Gen-V/VI Big Block V8 engines. MLS gaskets are known for their strength and ability to rebound, making them a solid choice for demanding applications. This gasket is designed to handle the heat and pressure found in these powerful V8s, ensuring a reliable seal between your cylinder head and engine block.

Cometic constructs this gasket using three to five layers of stainless steel. Stainless steel is chosen for its increased strength, its ability to resist corrosion, and its resilience under load. The outer layers of this gasket are embossed and then coated on both sides with a Viton rubber material. Viton is a high-performance synthetic rubber that can withstand temperatures up to 482°F (250°C), making it well-suited for the harsh sealing environments these engines can produce. This coating helps the gasket conform to surface imperfections and maintain a tight seal under various operating conditions.

This gasket fits a wide range of Chevrolet and GMC trucks from the early to mid-1990s, including models like the Chevrolet C1500, Chevrolet C2500 Suburban, and GMC K2500. It's a well-built component for anyone rebuilding or repairing the top end of their Gen-V/VI Big Block V8.
