Product Details

This is a Cometic copper head gasket designed for Chevrolet Mark-IV Big Block V8 engines. It features a 4.530-inch bore and a 0.043-inch thickness, making it suitable for a range of applications including classic Chevrolet Bel Air, Impala, and Chevelle models from the mid-60s through the mid-70s.

The gasket is constructed from copper, a material known for its ability to handle high temperatures and pressures common in performance Big Block engines. The outer layers are embossed and coated with Viton, a high-performance fluoroelastomer that helps create a strong, reliable seal against combustion gases and coolant. This updated construction aims for improved sealing performance over standard gaskets.
