Good luck in finding some, fitting headers on a transplanted engine like the 455 wouldn't be the hard part, fitting them in the Delta is, since it has the steering box behind the upper control arm. That leaves you little to go with. If you notice, mail order places have headers to fit the '71 and up Deltas with the 455 because the steering box is in front of the control arm. I don't have headers on my car because of that. I read someplace that Ed's has custom built headers that will fit, you will have to do a search on the internet for it though because I don't remember or have the link. It will cost you though. Good luck.
