About this part

Product Details

If you're rebuilding the top end of your 2006-2013 Chevrolet Corvette, a solid head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of the LS7 7.0L engine.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with both aluminum and cast iron blocks. This gasket has a compressed operating thickness of 0.045 inches and a bore size of 4.150 inches, designed to fit the LS7 engine precisely. Because it's an MLS design, it doesn't require any additional sealants.
