maunal vs. power steering with TTI headers

I am picking up my 1971 Dart GT from the shop today after they complete the install of TTI headers and full exhaust. The guy working in it had several issues which came up, but it (the Driver's side header) cleared the steering once he had the engine where it should be. I also bought a new mini-starter to accommodate the header as well.
Looking forward to driving it again, especially with the new gear on it.
