Cometic GM Gen-V/VI Big Block V8 .030in MLS Cylinder Head Gasket - 4.375in Bore

If you're working on a GM Gen-V or Gen-VI Big Block V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for sealing your cylinders. It's designed with a 4.375-inch bore and a compressed thickness of .030 inches, making it suitable for a wide range of Chevrolet and GMC trucks and vans from the early 90s through 2000, like the C1500, C2500 Suburban, and Express 3500.

What makes these MLS gaskets stand out is their construction. They're built from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs and various surface finishes without needing extra sealants. This makes them a great option whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as they can handle the shearing forces between different metals.
