Cometic GM LS Gen-3/4 Small Block V8 .027in MLS Cylinder Head Gasket - 3.970in Bore

When you're rebuilding the top end of your GM LS Gen-3/4 small block V8, you need a head gasket that can handle the pressure. This Cometic Multi-Layer Steel (MLS) gasket is built for that job. It's designed to seal reliably on a wide range of LS engines, including those found in vehicles like the Chevrolet Silverado, GMC Sierra, and Cadillac Escalade.

This gasket is constructed from multiple layers of stainless steel, giving it increased strength and the ability to rebound. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel, and its thickness is varied to achieve the desired compressed operating thickness, which is 0.036 inches for this specific gasket. This design means you don't need to use any additional sealants, and it's suitable for mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks.

With a 3.970-inch bore, this gasket is ready for your LS engine build. Cometic has been making gaskets for a long time, and their MLS design is a popular choice for high-output engines.
