Cometic Chevy Gen1 Small Block V8 .040in MLS Cylinder Head Gasket - 4.165in Bore - Vortec Heads

When you're rebuilding the top end of your Chevy Gen-1 Small Block V8, getting the cylinder head gasket right is crucial for sealing combustion and coolant passages. This Cometic Multi-Layer Steel (MLS) gasket is specifically designed for Vortec heads and features a 4.165-inch bore, with a compressed thickness of 0.040 inches. It's a well-built option that fits a wide range of GM vehicles from the early 80s, including popular models like the Chevrolet C10, Camaro, and GMC C1500.

What makes these MLS gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This advanced design means you don't need to use any sealants, and it works well whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can handle the shearing forces between different metals.
