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

The Viton coating on the outer layers of the gasket is a heat-resistant elastomer designed to meet the demands of harsh sealing environments. It can withstand high temperatures, up to 482°F, and works effectively with various surface finishes.

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

No, Cometic MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. They are engineered to seal effectively on their own.

What is the difference between MLS and traditional head gaskets?

Multi-Layer Steel (MLS) head gaskets, like this one, are made of multiple stainless steel layers for increased strength and rebound resistance. Traditional gaskets might be made of composite materials and may not offer the same level of durability or sealing performance in high-output engines.
