Cometic 2006+ GM LS7 7.0L 4.150 inch Bore .070 inch MLS-5 Head Gasket

If you're working on the LS7 engine in your 2006-2013 Chevrolet Corvette, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of that 7.0L powerhouse. It's designed for a 4.150-inch bore and has a compressed thickness of 0.070 inches, ensuring a solid seal between your cylinder head and engine block.

Cometic builds these gaskets with 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 temperatures up to 482°F (250°C) and works well with different surface finishes. This construction means the gasket can handle the shearing forces between aluminum heads and iron blocks without needing any extra sealants, making installation more straightforward.
