Cometic GM 3.1L 60 Deg V6 L82 91mm Bore .051in MLS Head Gasket

If you're rebuilding the top end of your GM 3.1L 60-degree V6 engine, getting the head gasket right is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures and temperatures involved in keeping your engine running smoothly.

This gasket is constructed with multiple layers of stainless steel, which gives it strength and resilience. The outer layers are coated with Viton, a synthetic rubber known for its resistance to heat and oil. When compressed, this gasket measures .051 inches thick, with a 91mm bore designed to match the L82/LG8 Gen-3 V6 engines. This well-built design helps ensure a reliable seal between the cylinder head and the engine block across a range of GM vehicles.

This gasket fits a wide variety of GM vehicles from the early to late 90s, including models like the Buick Regal, Chevrolet Lumina, and Pontiac Grand Prix. Always refer to your vehicle's specific service manual for proper installation procedures and torque specifications.
