Power Steering and B/RB in a '72 Duster?

Power steering is not a problem EXCEPT with headers (Check Schumacher headers, they may fit). My son's 67 Barracuda has power steering (383/4sp), my old 67 fastback had power steering (383/727). I will be putting power steering back in my 67 Barracuda convertible (440/727) and at some point my other son's 67 Dart GT convertible (440/4sp) will get power steering.

The common piece to all of those cars is cast iron exhaust manifolds (B-body HPs).

Also, it's not that I mind the manual steering, but good boxes are hard to find and expensive when you do find them. Even parking lots aren't that bad with manual. We went to power in my son's Barracuda for autocrossing because the 24:1 manual box just had too many turns lock-lock. Power is going back in my convertible so that my wife will have an easier time driving it (she hasn't had the pleasure of driving one of the big block cars, but used to drive the 340 GTS convertible daily).
