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

MLS head gaskets, like this Cometic C5456-070, are constructed from multiple stainless steel layers. This design provides greater strength, better resistance to corrosion, and improved sealing performance compared to older gasket types, especially in high-output engines.

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

No, Cometic MLS head gaskets are designed to provide maximum sealing performance on their own. They do not require any additional sealants, which simplifies the installation process.

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

Viton is a type of synthetic rubber that is highly resistant to heat, up to 482°F (250°C). It's used as a coating on the outer layers of this gasket to ensure a durable and reliable seal in demanding engine conditions and on various surface finishes.

About this part

Product Details

If you're working on a Chrysler LA V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the job. It's designed with a 4.180-inch bore and a compressed thickness of 0.070 inches, making it suitable for a wide range of Chrysler, Dodge, and Plymouth V8 applications from the mid-60s through the early 90s, including models like the Dodge D150 and Chrysler Cordoba.

Cometic's MLS design uses multiple embossed stainless steel layers for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, ensuring a reliable seal without needing additional sealants. This construction is ideal for engines using aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals.
