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

MLS head gaskets offer increased strength and durability due to their layered stainless steel construction. This design allows the gasket to rebound and resist corrosion, providing a reliable seal for high-output engines.

What is Viton coating and why is it used on this gasket?

Viton is a heat-resistant rubber material that can withstand high temperatures, up to 482°F (250°C). It's used on the outer layers of this gasket to meet the demands of harsh sealing environments and ensure a long-lasting seal.

Does this gasket require any special installation procedures or sealants?

No, this Cometic MLS head gasket is designed to provide maximum sealing performance without the need for additional sealants. Always refer to the manufacturer's installation instructions for specific details.

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 AMC 390 and 401 Gen-3 V8 engines and is specifically sized at 4.380 inches for the bore and is .030 inches undersize, which is important for proper engine assembly. This gasket is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder heads and engine block.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel for strength and corrosion resistance, allowing it to rebound and maintain its seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and works well with both aluminum and cast iron components. The compressed thickness is 0.098 inches, and it's designed to seal effectively without needing any extra sealants, making installation more straightforward. This type of gasket is ideal for engines that see a lot of use, whether you're rebuilding a classic Jeep Wagoneer or an American Motors AMX.
