What is the advantage of a Multi-Layer Steel (MLS) head gasket?

MLS head gaskets are made of multiple stainless steel layers, which provides increased strength and resilience. This construction helps them rebound and resist corrosion, making them ideal for high-output engines.

Do I need to use sealant with this Cometic head gasket?

No, this Cometic MLS head gasket is designed to provide maximum sealing performance without the need for additional sealants. The Viton coating on the outer layers ensures a reliable seal on its own.

Can this gasket be used with different head and block materials?

Yes, this gasket is suitable for both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks. It's engineered to withstand the shearing forces that can occur between these different materials.

About this part

Product Details

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed for GM Gen-V/VI Big Block V8 engines, offering a 4.540-inch bore and a compressed thickness of .051 inches. This gasket is built to handle the demands of high-output engines, ensuring a strong seal between your cylinder heads and block.

This MLS gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well with different sealing environments and surface finishes. This construction means the gasket requires no additional sealants, making installation more straightforward. It's suitable for use with both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks, as it can manage the shearing forces that can occur between dissimilar metals.

This gasket fits a range of vehicles, including models like the Chevrolet C1500 and GMC C2500 Suburban. It's a solid option for anyone rebuilding or working on the top end of their GM Big Block V8.
