Cometic Buick 3.8L V6 Ser.2 3.840in Bore .066 inch MLS LHS Head Gasket

If you're working on the 3.8L V6 Series II or III engine in a variety of GM vehicles, this Cometic Multi-Layer Steel (MLS) head gasket is what you need for the left side. It's designed with a 3.840-inch bore and a compressed thickness of 0.066 inches, making it a precise fit for these popular engines found in cars like the Buick LeSabre, Chevrolet Camaro, and Pontiac Grand Prix.

This gasket is built from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction means the gasket seals effectively without needing any extra sealants, and it works well whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.066 inches on this specific gasket.
