About this part

Product Details

If you're rebuilding the top end of your 2006-2013 Chevrolet Corvette, specifically with the LS7 7.0L engine, a reliable head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of high-output engines, ensuring a strong seal between your cylinder heads and engine block.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps create a robust seal, even with aluminum heads on aluminum or cast iron blocks, and it means you don't need to use additional sealants during installation. The center layer is stainless steel and can be varied in thickness; this particular gasket has a compressed operating thickness of .098 inches, with a 4.150-inch bore to match the LS7 engine.

This gasket is designed as a direct fit for the specified Chevrolet Corvette models. Ensure your engine block and cylinder heads are clean and properly prepared before installation, as MLS gaskets require a smooth, flat surface for optimal performance.
