Ford FE Factory1962 - 1964 Ford Long Tube Cast Iron Headers. I have owned this pair since the late 1970's. They have been installed in a 1964 Galaxie with 352, 390, and 428 engine sizes. The right side header is C2AE 8430 B. The left side header is C3AE 9431 D. They have been cleaned and conditioned with Calyx manifold coating. Prior to my ownership the left side header was used in a later year model and one tube of the manifold was sectioned to clear some part in the engine compartment. I took that header to a welding shop where the header was heated in a furnace and the portion of the inverted tube was restored with brazing. Both headers were surfaced to fit flat on the engine heads. I have run this set on multiple engines over the years with no leaks or issues.
