What does MLS construction mean for this gasket?

MLS stands for Multi-Layer Steel. This construction uses several layers of stainless steel to create a strong, durable gasket that can handle high pressures and temperatures while resisting corrosion.

What is the purpose of the Viton coating?

The Viton coating on the outer layers helps the gasket create a tight seal, even on surfaces that aren't perfectly smooth. It's also heat-resistant, able to withstand temperatures up to 482°F, making it suitable for demanding engine conditions.

Does this gasket come with any hardware?

This product is for the cylinder head gasket only. It does not include head bolts or other installation hardware, which should be sourced separately if needed.

About this part

Product Details

When you're rebuilding the top end of your GM Gen-V or VI Big Block V8, you need a head gasket that can handle the job. This Cometic MLS (Multi-Layer Steel) gasket is built for those engines, featuring a 4.540-inch bore and a .098-inch thickness. It's designed to create a solid seal between your cylinder head and engine block, which is crucial for maintaining compression and preventing leaks.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel, which gives it increased strength and the ability to rebound and resist corrosion. The outer layers are coated on both sides with Viton, a high-temperature rubber material that can withstand up to 482°F. This coating helps it seal effectively even in tough conditions and on various surface finishes.

This gasket fits a range of Chevrolet and GMC trucks and vans from the early to mid-90s, including models like the Chevrolet C1500, GMC K2500 Suburban, and Chevrolet P30. It's a well-built component for anyone working on these specific Big Block V8 engines.
