What is the compressed thickness of this head gasket?

This Cometic MLS head gasket has a compressed operating thickness of 0.060 inches. This specific thickness is designed to work with the factory specifications for the LS7 7.0L engine in your Corvette or Camaro.

Does this gasket require any sealant?

No, Cometic MLS head gaskets are designed for maximum sealing performance and do not require any additional sealants. The Viton coating on the outer layers helps create a tight seal on its own.

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

Viton is a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C). It's used on the outer layers of this gasket to meet the demands of harsh sealing environments and ensure a reliable seal against combustion pressures and engine fluids.

About this part

Product Details

If you're working on a 2006-2013 Chevrolet Corvette with the LS7 7.0L engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to seal your cylinder heads tight. It's specifically made for a 4.150-inch bore and has a compressed thickness of 0.060 inches, which is a common spec for these high-output engines.

Cometic builds these gaskets with multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs and different surface finishes without needing extra sealants. The center layer is also stainless steel and can be varied in thickness, which is how Cometic achieves the specific 0.060-inch compressed thickness for this gasket. This construction helps them withstand the forces between aluminum heads and cast-iron blocks.
