68 dart with 383

I am looking to put headers on my dart which will be getting a 383 and 727 TF swapped into it soon. The car has power steering and a column shifter. This has been making it hard for me to find what will actually fit. My original plan was to get the tti shorty headers found here: http://www.ttiexhaust.com/MoparClassics-Headers/44025-Shorty/TTi44025.htm
However, when I called them, they informed me that they are unsure if these headers will have clearance issues with the column shifter. Have any of you put these on running a column shifter? If any of you are running a big block with power steering and a column shifter, what are you using for exhaust? Thank you in advance.
