Cometic 2006+ GM LS7 7.0L 4.150 inch Bore .080 inch MLS-5 Head Gasket

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 what you need to seal the combustion chamber. It's built to handle the demands of high-output engines, ensuring a reliable seal between the cylinder head and the engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The compressed thickness is .080 inches, and the bore size is 4.150 inches, specifically designed for the LS7 engine. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.

These MLS gaskets are suitable for combinations of aluminum heads with aluminum blocks, or aluminum heads with cast iron blocks, as they can manage the shearing forces that can occur between different metals. The center layer is stainless steel and can be varied in thickness to meet different requirements, though this specific gasket is set at .080 inches.
