Cometic GM Gen-V/VI Big Block V8 .040in MLS Cylinder Head Gasket - 4.500in Bore

Cometic Gasket is well-known for making reliable sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built specifically for GM Gen-V/VI Big Block V8 engines and features a 4.500-inch bore with a thickness of .040 inches. This gasket is designed to handle the demands of high-output engines, ensuring a strong seal between your cylinder head and block.

What makes these MLS gaskets stand out is their construction. They’re made from multiple layers of stainless steel, which gives them increased strength and the ability to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in tough sealing environments. This design means you don't need any extra sealants, and it’s effective whether you're pairing aluminum heads with aluminum blocks or aluminum heads with cast iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .040 inches on this particular gasket, which has a compressed operating thickness of .036 inches.

This gasket fits a range of vehicles, including models like the Chevrolet C1500, GMC C2500 Suburban, and Chevrolet P30. It's a solid option when you need dependable sealing for your big block V8.
