Advice on 440 into 74 Duster exhaust

I was wondering what my best option here is as far as fitment for my swap coming up. Before i went spending any money i wanted to see if anyone has tried fitting shorty headers, or more specifically, 1-3/4" Shorty Headers
For an RB swap?

I know the header question comes up often but i don't see many talking about using shorty headers.
For my application i wanted to use power steering and a column shifter. I don't know if there is a way to avoid cutting up the tube on the steering column but I currently have a 69 C body HP drivers side manifold and a passenger side truck log manifold. These use to be accepted as the most painless way to fit an RB into a duster but it now looks like people are saying that they have fitment issues as well. I'm not looking for power, i have a slightly cammed 440 motorhome boat anchor and that's just fine. Does anyone have an opinion on what i should do?
