Product Details
When you're rebuilding the top end of your GM LS Gen-3 or Gen-4 small block V8, a solid head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built for engines with a 4.130-inch bore and a thickness of .066 inches, designed to handle the demands of these popular V8s. You get one head gasket in this package, ready to seal the combustion chamber and coolant passages.
The outer layers of this gasket are embossed and coated with Viton, a high-performance fluoroelastomer. This coating helps the gasket conform to the cylinder head and block surfaces, creating a strong seal that resists blow-by and coolant leaks, even under higher pressures. MLS construction itself offers a robust barrier, making it a popular choice for many LS engine builds.
This gasket fits a wide range of GM vehicles, including models like the Chevrolet Corvette, Camaro, and Silverado. Always double-check the fitment guide to ensure it's the right choice for your specific application.
