I will guess... |

I believe it was only factory original on the 1965 427 Galaxie.
I don't have time to dig through my records right now, but if those are the long tube headers, they're for the 1965-later Galaxie applications.
Long tube fitments are different between the 1961-64 frame and the 1965-70 frames, so different long tube header versions were cast. I believe some slight frame changes may have happened in the late 1960s, so 1968-later Galaxies might possibly have a component that interferes, maybe not.
The long tube header was dropped in 1966 in favor of the smaller and cheaper 1966 Fairlane 427 "fan" manifold design. When the fan manifold became available for the 427 Fairlane, 427 Galaxies inherited it, but the long-tube was still available over-the-counter.
I wish I had quicker access to my exhaust info, but this preliminary guesswork might help a bit.
Shoe.
