68 cuda 383 exhaust manifold removal

All of the folks that have Gen 2 cudas with a BB, I have a question regarding left side exhaust manifold removal. It appears to me that I will have to remove/relocate the steering column. The service manual is not real clear on this to me and am asking how much of pain that is to do. Just looking for any tips or tricks and lessons learned.
Next question is in regards to headers. Do the ones from TTI fit with little or no modifications. Or are there others out there that will fit without going thru the fender wells or other modifications. I do have the mini high torque starter installed and have 727 trans with consel shift. Thanks and if this has been talked about before, sorry, I could not find it with a search of the site.
