Header options for the 440?

I have been looking around briefly at headers available for the 440 in an A body. TTI has footnotes stating that power steering can't be used and that tremec transmissions can't be used. Both are these are option I was looking at for my dart. When they state no power steering, does this take into count a set up like the alteKation and a rack & pinion set up? If I go with a 440, alterk, and tremec set up on my project. What are my options for headers?

Thanks
