best headers??

I swapped out my 71 steering box and linkage with a 73 and up box and linkage. Will this make any difference in fitment of headers, mainly around the steering gear box area? I just put a set of headmans on my 71 and I hate them and wish I never spent money on them. I have zero miles on them and am wanting to replace them already. After seeing the clearance and how thick the flange is not to mention spark plugs wire routing on the tti and dougs I want to replace them before I ever use them.
