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

MLS head gaskets are made of multiple stainless steel layers, which gives them increased strength and the ability to rebound. This construction helps them resist corrosion and provides reliable sealing for high-output engines without needing additional sealants.

What is the purpose of the Viton coating on the outer layers?

The Viton coating is a heat-resistant rubber material that can withstand temperatures up to 482°F. It's designed to meet the demands of harsh sealing environments and various surface finishes, ensuring a durable seal.

Can this gasket be used with different types of engine blocks and heads?

Yes, MLS gaskets like this one are suitable for use with aluminum heads on aluminum blocks, as well as aluminum heads on cast iron blocks. They are designed to handle the shearing forces that can occur between different materials.

About this part

Product Details

Cometic Gasket is a well-known name for creating reliable sealing components, and this Multi-Layer Steel (MLS) head gasket is built for serious performance. If you're working on a Chevrolet Mark-IV or GM Gen-V/VI Big Block V8, this gasket is designed to handle the demands of high-output engines. It features a compressed thickness of .080 inches and a bore size of 4.570 inches, making it suitable for aftermarket heads and offering flexibility with its undersized water ports for customization.

This 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 embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This Viton coating is designed to meet the challenges of harsh sealing environments and varying surface finishes. The center layer is uncoated stainless steel, allowing for adjustments to thickness requirements. Because it's an MLS gasket, it doesn't require any additional sealants and works well with both aluminum and cast iron blocks, and aluminum or cast iron heads.

This gasket fits a wide range of vehicles, including models like the Chevrolet Impala, Corvette, and C10 Pickup from various years. It's a solid option for rebuilding or upgrading your Big Block V8 engine.
