Cometic GM LS9/LSA Gen-4 Small Block V8 .040in MLX Cylinder Head Gasket 4.100in Bore LHS

Cometic Gasket is well-known for making durable sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on your 2009-2015 Cadillac CTS, especially if it's a high-output Gen-4 Small Block V8 like the LS9 or LSA, this gasket is built to handle the pressure. It's designed to provide maximum sealing performance without needing any extra sealants, making the job cleaner and more reliable.

This gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different engine materials like aluminum and cast iron. The center layer is also stainless steel, and its thickness can be adjusted to meet specific requirements; in this case, it's set to provide a compressed thickness of 0.098 inches with a 4.100-inch bore, and it's specifically 0.040 inches undersize.
