440 A body headers

Probably the number one hurdle for the B/RB is the Exhaust situation. You won't go wrong with the Schumacher headers but it leaves some power on the table. I am only guessing that if TTI or anyone else could make something different to accommodate Powersteering, easier plug access, and a full tube design they would. Unless you have a specific need for the bigger power you will be fine with the Tri-y's.
