Help! Doug's headers in 67 barracuda

Thanks for all the help and suggestions.
They are in and so far so good. Unfortunately I had to grind down a bit of the Borgeson Powersteering box and dent the header tube to create enough clearance. (fortunately you can't really see it). I also had to dent the #7 tube to clear the steering column (only a problem for '67 vehicle) I also had to clearance the pipes around the torsion bar. The only modifications needed were on the drivers side. I dented the headers with a very large Socket wrapped in tape so it wouldn't scratch the pipes. The dents worked out pretty well. Hated to have to do it, but I guess that's why they call it Hot rodding. Probably would never have been an issue if the car was stock. My car is a 67 but runs '74+ k member and aftermarket steering pump etc.

For what it's worth, I'm installing Doug 453, 68 Barracuda, 340, factory K, new factory biscuits, same Borgeson Box, same problem you had at #1 tube. Have not attempted shifting engine yet.
