What is the primary benefit of the multi-layer steel (MLS) construction?

The multi-layer steel construction provides increased strength and better resistance to rebound compared to single-layer gaskets. This helps ensure a more reliable seal between the cylinder head and the engine block.

What is the purpose of the Viton coating on the gasket?

The Viton coating on the outer layers helps the gasket meet the demands of harsh sealing environments and various surface finishes. It is also heat resistant up to 482°F (250°C), contributing to a durable seal.

Does this gasket come with any installation hardware?

This product is for the cylinder head gasket only. Installation hardware, such as head bolts or studs, is typically sold separately and should be checked for compatibility with your specific engine build.
