Headers with coil over K member

I'm curious on what brand of header the guys that may have a RMS, or HDK type conversion are running on their engines, B or RB either one. I'm really wondering if Doug's B or E body units will have issues fitting once the torsion setup is removed. There has to be more available than just TTI or some fender exits, since I'm not really wanting to cut mine up.

I have a magnum force front end, and run the (used) TTI 2'' headers , I have been wondering about the Dougs , coated, B body headers too .
