Cometic GM LSX Gen-4 Small Block V8 .066in MLS Cylinder Head Gasket - 4.185in Bore - LHS

Cometic Gasket is a well-known name for creating dependable sealing products, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s specifically made for GM LSX Gen-4 Small Block V8 engines and is designed to handle the demands of high-output applications. This gasket is crucial for maintaining proper compression and preventing leaks between your cylinder head and engine block, which is vital for your engine's performance and longevity.

This gasket is constructed from multiple layers of stainless steel, giving it increased strength and the ability to rebound and resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is designed to work effectively in harsh sealing environments and with various surface finishes, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. The center layer is stainless steel and can be varied to achieve different thickness requirements, like the .066 inch thickness on this particular gasket, which is important for maintaining precise engine tolerances.

Because these are MLS gaskets, they don't require any additional sealants, simplifying the installation process. They are built to withstand the shearing forces that can occur when mating different metal types, like aluminum heads to cast iron blocks.
