What is the primary purpose of a Multi-Layer Steel (MLS) head gasket?

An MLS head gasket is designed to provide a strong and reliable seal between the engine block and cylinder head. Its layered construction helps maintain sealing integrity under high temperatures and pressures common in modern engines.

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

Viton is a type of high-performance synthetic rubber known for its excellent resistance to heat and various fluids. Coating the gasket with Viton helps it withstand high engine temperatures and create a durable seal against combustion gases and coolant.

Does this gasket come with any installation hardware?

This product is for the cylinder head gasket only. It does not include head bolts or other installation hardware, which should be sourced separately if needed.
