What is the benefit of Multi-Layer Steel (MLS) head gaskets?

MLS head gaskets are made from multiple layers of stainless steel, which gives them increased strength and the ability to rebound. This construction also helps them resist corrosion and handle the shearing forces between different block and head materials.

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

No, Cometic MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. Their construction and Viton coating ensure a reliable seal on their own.

What is the Viton coating on the outer layers for?

The Viton coating is a heat-resistant elastomer that can withstand high temperatures, up to 482°F (250°C). It's designed to meet the demands of harsh sealing environments and ensures a durable seal between the cylinder head and the engine block.

About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring a Viton rubber coating on the outer layers. With a compressed operating thickness of 0.070 inches and a 4.100-inch bore, it's designed to provide maximum sealing performance for high-output GM LT1 and LT4 Gen-2 Small Block V8 engines. These gaskets are well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as they can handle the shearing forces that can occur between dissimilar metals.

The strength of MLS gaskets comes from their layered stainless steel construction, which also allows them to rebound and resist corrosion. The Viton coating on the outer layers is a heat-resistant elastomer capable of withstanding temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments. The center layer is uncoated stainless steel and can be varied to achieve different gasket thicknesses, like the 0.070-inch specification on this particular gasket. Because of their construction, these MLS gaskets do not require any additional sealants for installation.

This head gasket fits a range of GM vehicles from the early to mid-90s, including models like the Chevrolet Camaro, Corvette, and Pontiac Firebird. It's a solid option when you're rebuilding the top end of your LT1 or LT4 engine and need a reliable seal.
