What does MLS mean for a head gasket?

MLS stands for Multi-Layer Steel. This construction uses several layers of stainless steel to create a strong, durable gasket that can handle high pressures and temperatures. It's a popular choice for modern engines.

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

Viton is a type of synthetic rubber that is highly resistant to heat and various fluids. On this gasket, the Viton coating helps create a tight seal against the cylinder head and block surfaces, even in harsh engine conditions and at temperatures up to 482°F (250°C).

Does this gasket come with any hardware?

This product is for the head gasket only. Head bolts are typically sold separately and should be replaced with new ones when installing a new head gasket, following the manufacturer's torque specifications.

Product Details

This is the right-hand side head gasket for your 2006-2008 Chevrolet Impala, specifically for the LZE/LZ4 V6 engine. It's a Multi-Layer Steel (MLS) gasket, measuring 101mm across the bore and .051 inches thick, designed to seal the combustion chamber and coolant passages between the cylinder head and the engine block.

Cometic builds these gaskets with multiple layers of stainless steel for added strength and resistance to corrosion. The outer layers are treated with a Viton rubber coating on both sides. This coating is heat resistant up to 482°F (250°C) and helps the gasket conform to the surfaces it seals, even under tough conditions and varying pressures. This well-built gasket is a solid option for rebuilding or repairing your engine's top end.
