Cometic Chevrolet Gen-1 Small Block V8 .051in MLS Cylinder Head Gasket 4.200in 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 solid seal without needing extra sealants.

Cometic builds 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 can handle tough sealing environments and different surface finishes, making them suitable for combinations like aluminum heads on cast iron blocks. This particular gasket has a compressed thickness of .051 inches and a 4.200-inch bore, and it's designed for aftermarket heads with undersized water ports that allow for custom fitting.

This gasket fits a wide range of Chevrolet and GMC trucks, cars, and SUVs from the early 80s, as well as some Avanti, Checker, and Excalibur models. It's a well-built option for anyone looking to ensure a reliable seal on their V8 rebuild.
