Cometic Chevy Small Block 4.060 inch Bore .027 inch MLS Head Gasket (18 or 23 Deg. Heads)

Cometic Gasket has a solid reputation for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a Chevrolet Gen-1 Small Block V8 engine, especially one with a 4.060 inch bore and either 18 or 23-degree cylinder heads, this gasket is designed to provide a strong seal. It's built to handle the demands of higher output engines, ensuring reliable performance without needing additional sealants.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The compressed operating thickness is 0.027 inches, and the center layer can be varied to meet different thickness requirements. 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 dissimilar metals.
