Sanderson DD7 Headers or TTI "step"

Thank You Keith Mopar for your input ... I like the TTI's, but I am concerned about my future plans of adding fast ratio steering. Unless I can get some info here on Sanderson DD7's or dig up some somewhere else, I will more than likely buy and install the TTI step headers with the recommended mini starter. I almost wish I had not seen the Sanderson shorty headers, this would have been a done deal. It just looks like the Sanderson DD7's give me more options for the future ... I just need some information .. I thought for sure someone on here would have purchased and installed the DD7's, and perhaps had some photo's. No sense in beating a dead horse ... I guess I need to quit asking here and look for answers elsewhere. I do want to thank you all for taking the time to reply. Long live the "A" body ... what a fun car to own, the 340 is a fantastic little small block.
