What does the MLX technology do?

MLX technology uses an integrated stopper layer to improve sealing around the combustion chamber and increase clamp load on the cylinder. This helps ensure a solid seal without causing distortion to the cylinder bore.

Does this gasket require sealants?

No, this Cometic MLX head gasket does not require any additional sealants. It is designed to provide a complete seal on its own, and no re-torque procedure is needed after installation.

What is the benefit of the Viton coating?

The Viton coating on both sides of the gasket offers improved sealing performance and resistance to high temperatures and various chemicals. This contributes to the gasket's overall durability and effectiveness in harsh engine conditions.

About this part

Product Details

This Cometic MLX head gasket is designed for GM L83, L8B, L82, and L84 Gen-V small block V8 engines. It features a 3.875-inch bore and a .058-inch thickness, providing a precise fit for these specific V8 applications. This gasket is built to ensure a solid seal between the cylinder head and the engine block.

The MLX (Multi-Layer Stopper) technology used in this gasket incorporates an integrated stopper layer. This layer helps create a strong seal around the combustion chamber and increases the clamping force on the cylinder without causing distortion. It's made from the same well-regarded materials as Cometic's MLS head gaskets, offering a durable and reliable seal. You won't need to use any additional sealants or perform a re-torque procedure after installation.

This gasket is coated on both sides with Viton, a high-performance fluoroelastomer known for its resistance to heat and chemicals, further enhancing its sealing capabilities and longevity. It fits a range of vehicles, including models like the Chevrolet Corvette, Silverado 1500, and GMC Sierra 1500.
