Cometic Chevrolet Gen-1 Small Block V8 .027in MLS Cylinder Head Gasket - 4.125in Bore

If you're working on a Chevrolet Gen-1 Small Block V8 and need a solid head gasket, this Cometic MLS gasket is a popular choice. It's designed for a 4.125-inch bore and a compressed thickness of 0.027 inches, making it suitable for a wide range of vehicles from the early 80s, like the Chevrolet C10 or Camaro, and even some Buick models. This gasket is built to handle the demands of higher output engines, ensuring a reliable seal between your cylinder head and block.

What sets this gasket apart is its Multi-Layer Steel (MLS) construction. It uses multiple layers of stainless steel for increased strength and resistance to corrosion, which is important when mating different metals like aluminum heads to cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes without needing additional sealants. The center layer is also stainless steel, allowing for precise thickness control. This gasket also features undersized water ports, which is a practical detail for aftermarket heads, giving you room for custom port matching.
