Cometic Ford Big Block 429/460 4.520in Bore 0.043in Copper Head Gasket

This is a Cometic copper head gasket designed for Ford Big Block 429 and 460 engines. It features a 4.520-inch bore and a 0.043-inch thickness, making it suitable for specific engine builds where precise sealing is critical. This gasket is built to handle the demands of these powerful V8 engines.

The gasket is constructed from copper, a material known for its ability to conform to engine surfaces and create a tight seal under high pressure and temperature. Cometic has applied an embossed outer layer coated with Viton, a high-performance fluoroelastomer, to enhance sealing capabilities and resistance to combustion byproducts. This combination helps ensure a reliable seal between the cylinder head and the engine block, crucial for maintaining compression and preventing leaks.

This gasket fits a wide range of Ford and Lincoln vehicles from the late 1960s through the 1990s, including models like the Ford F-250, E-350 Econoline, and Lincoln Continental. Always confirm fitment for your specific year and model.
