Big Block Truck Headers/Exhaust manifolds

Ok, I blew up my Ford Explorer and got laid off, so I am now up to my nose in motor swap. I got the swap mounts ordered today. I picked up a few tools so I can pop my steering box out. Anyone know how to tell if it is a standard or reverse rotation steering gear? I have a hard time believing I have to spend almost $600 on new headers for my truck. Does anyone that replied happen to still have the BB truck headers that were mentioned?
