The Cometic Ford Big Block 429/460 4.520in Bore 0.043in Copper Head Gasket - C15421-043 is a precision-engineered head gasket with a 4.520" bore and .520" compressed thickness.

The Cometic Copper head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Copper construction, this gasket uses solid copper construction for custom thickness adjustment and superior thermal conductivity. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
