I used Hedman tight tubes in the beginning and modified the drive side to fit without power steering. I did not have to touch the passenger side. Getting around the steering linkage was a plumber's nightmare!
63Morepar could you tell me what modifications you did to the Hedman tight tubes headers to make them fit with out power steering?
Again, did not have to touch the passenger side header on my '63/340.
I tried to "dimple" the drivers side to fit, but no way! I cut out the #1 pipe from the collector, used a hole saw and cut a hole in the # 5 pipe. Whacked off the corner of the collector and plated it off. Connected cyl. 1 to the new hole in # 5 cyl. I had them recoated and they fit well.
I added some photos.
