Cometic GM LS Gen-3/4 Small Block V8 .056in MLS Cylinder Head Gasket - 4.060in Bore

Starting with a .056 inch compressed thickness and a 4.060 inch bore, this Cometic Multi-Layer Steel (MLS) head gasket is built for GM LS Gen-3 and Gen-4 small block V8 engines. These gaskets are designed to handle the demands of high-output engines, providing a strong seal without needing additional sealants. They work well with both aluminum and cast iron blocks, and are constructed to resist the shearing forces that can occur between different metal types.

The multi-layer steel construction offers increased strength and resilience, with outer layers coated in Viton, a heat-resistant synthetic rubber that can handle temperatures up to 482 degrees Fahrenheit. This coating is designed to perform in tough sealing environments and on various surface finishes. The center layer is stainless steel, allowing for different thickness options to suit specific engine builds. This design helps ensure a reliable seal for your engine's top end.

This gasket fits a wide range of vehicles, including popular models like the Chevrolet Silverado 1500, Cadillac CTS, and Chevrolet Corvette. It's a solid option when you're rebuilding or refreshing the top end of your LS engine.
