Cometic GM LS Gen-3/4 Small Block V8 .073in MLS Cylinder Head Gasket - 4.060in Bore

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed specifically for GM LS Gen-3/4 Small Block V8 engines, featuring a 4.060-inch bore and a compressed thickness of .073 inches. This gasket is built to handle the demands of high-output engines, ensuring a solid 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 rebound, helping to resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This design means you don't need any extra sealants, and it works well whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces between different metals. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .073 inches on this particular gasket.

This gasket fits a wide range of vehicles, including popular models like the Chevrolet Corvette, Cadillac CTS, and Chevrolet Silverado 1500. It’s a solid option for anyone rebuilding or upgrading their LS engine.
