Cometic Chevy Small Block 4.165 inch Bore .098 inch MLS-5 Head Gasket (w/All Steam Holes)

If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, a solid head gasket is crucial for sealing combustion pressure and coolant. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines, offering a reliable seal without needing extra sealants.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes, making it suitable for combinations of aluminum and cast iron blocks and heads. This particular gasket has a 4.165-inch bore and a compressed thickness of 0.098 inches, with all steam holes included to help manage heat.

This gasket fits a wide range of vehicles from the early 1980s, including popular models like the Chevrolet C10, Camaro, and Corvette, as well as GMC trucks. It's a well-built option for anyone looking for a durable seal on their small block Chevy rebuild.
