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

MLS head gaskets, like this Cometic C5330-067, offer increased strength and better resistance to corrosion compared to traditional composite gaskets. They are designed to handle higher pressures and temperatures, providing a more reliable seal for your engine.

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

The Viton rubber coating on both sides of the gasket helps create a superior seal. It's heat resistant up to 482°F (250°C) and is designed to meet the demands of harsh sealing environments and varying load conditions, ensuring a tight seal between the cylinder head and block.

Does this gasket come with any hardware or sealant?

This Cometic head gasket is sold individually and does not include additional hardware or sealant. It is designed to be installed with appropriate head bolts and may require specific surface preparation as per the manufacturer's instructions.
