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

An MLS head gasket uses multiple layers of stainless steel to create a strong and durable seal between the engine block and cylinder head. This design offers better resistance to heat and pressure compared to older gasket types.

What does the Viton coating do?

The Viton rubber coating on the outer layers of the gasket helps it seal effectively against various surface finishes and under different load conditions. It's also heat resistant, capable of withstanding temperatures up to 482°F.

Does this gasket come with any hardware?

This product includes the Cometic MLS head gasket itself. It is recommended to use new head bolts when installing a new head gasket, as they are often torque-to-yield and should be replaced according to manufacturer specifications.
