Cometic Chevy Small Block 4.165 inch Bore .140 inch MLS Head Gasket (w/All Steam Holes)

Starting with a multi-layer steel (MLS) construction, this Cometic head gasket is built for serious sealing. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle up to 482 degrees Fahrenheit, making it ideal for sealing aluminum heads to either aluminum or cast iron blocks. This design helps prevent shearing forces that can occur between different metals.

The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements; in this case, it's set at a compressed operating thickness of 0.140 inches. This gasket also includes all steam holes, which are important for managing heat and pressure within the engine. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation. It's a well-built option for a wide range of Chevrolet Gen-1 Small Block V8 engines, including those found in vehicles like the Chevrolet C10 and Camaro from the early to mid-1980s.
