Cometic GM LS Gen-3/4 Small Block V8 .080in MLS Cylinder Head Gasket - 4.060in Bore

Starting with a compressed thickness of just 0.036 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing on GM LS Gen-3 and Gen-4 small block V8 engines. It’s designed with a 4.060-inch bore, making it suitable for a wide range of popular vehicles, including models like the Chevrolet Corvette, Cadillac CTS, and Chevrolet Silverado 1500. These gaskets are essential for ensuring a tight seal between your cylinder heads and engine block, especially in high-output applications where stock gaskets might struggle.

The strength of these MLS gaskets comes from their multiple layers of stainless steel, which also helps them resist corrosion and maintain their shape under stress. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This Viton coating is crucial for meeting the demands of harsh sealing environments and varied surface finishes, ensuring a reliable seal whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks. The center layer is stainless steel, allowing for precise thickness control to meet specific engine build requirements.

Because they are designed for maximum sealing performance, these Cometic MLS head gaskets do not require any additional sealants, simplifying installation. They are a solid option for anyone rebuilding or modifying their LS engine and looking for dependable sealing performance.
