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

MLS head gaskets offer a more robust seal compared to traditional composite gaskets. They are better at handling higher cylinder pressures and temperatures, which is beneficial for many engine builds.

What does the Viton coating on the outer layers do?

The Viton coating on the embossed outer layers helps create a more reliable seal against the cylinder head and block surfaces. Viton is known for its resistance to heat and engine fluids, contributing to the gasket's longevity.

Does this gasket come with any hardware?

This product is for the cylinder head gasket only. You will need to source head bolts separately, and it is recommended to use new head bolts when installing a new head gasket.
