If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, this Cometic MLS cylinder head gasket is a solid choice. It's designed for engines with 4.125-inch bores and is precisely 0.040 inches thick, making it suitable for 18/23 degree cylinder heads. This gasket is built to handle the demands of these popular V8s found in a wide range of vehicles, from Chevrolet C10 and Camaro models to GMC C1500 trucks and even the Chevrolet Corvette.
