Cometic Chevrolet Gen-1 Small Block V8 .036in MLS Cylinder Head Gasket - 4.160in Bore

If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, getting the head gaskets right is crucial for sealing combustion and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines, offering a reliable seal between your block and aftermarket cylinder heads.

Cometic constructs these gaskets with multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that seals effectively against various surface finishes and conditions, even with aluminum heads on iron blocks. This gasket has a compressed operating thickness of .036 inches and a 4.160-inch bore, designed to work with aftermarket heads and featuring undersized water ports that allow for customization to your specific setup. They require no additional sealants, making installation more straightforward.

This gasket is a solid option for a wide range of vehicles from the early 80s, including models like the Chevrolet Camaro, GMC C1500, and Buick Regal. Ensure your cylinder heads are compatible with a 4.160-inch bore and consider the specific requirements for your engine build.
