Cometic 96-03 Buick V6 3800 SER.2 3.84in .040inch MLS LHS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.040 inches, designed for specific engine builds where that precise dimension is needed. It's the left-side gasket for Buick V6 3800 Series II and III engines, commonly found in vehicles like the Buick LeSabre, Pontiac Grand Prix, and Chevrolet Camaro from the mid-90s through the mid-2000s.

MLS gaskets are well-built for high-output engines because they're made from multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and works well with both aluminum and cast iron engine blocks. This construction means the gasket seals effectively without needing any extra sealants, making installation more straightforward.

The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the 0.040 inches on this particular gasket. This attention to material and construction helps ensure a solid seal for your engine's top end.
