You cannot interchange front to rear O2 sensors. They do two completely different things.
Install your OEM front O2 sensors in the two front bungs of your headers and install the wires to the sensors (you will need to use wire extensions)
Cap off the two rear bungs on your new headers. Your OEM rear O2 sensors will not be used. The wires for the rear O2 sensors don't get attached to anything (tuck them out of the way)
Have your tuner do a 'rear O2 sensor delete' with his tuning software so you don't get a check engine light
All done ...

What do you mean by "aftermarket O2 sensors"? Your car stock should have 2 front O2 sensors and 2 rear O2 sensors. You install these in the headers the same way as stock; fronts in the front, rears further back typically after the cats if you have a catted X-pipe. (If there are no rear O2 sensor bungs, you leave them out and will have to get a tune to turn off the rear sensors and error codes).
There shouldn't be any need for any "aftermarket O2 sensors". (You may need O2 sensor wire extensions if your headers did not come with them).
Now if your "aftermarket O2 sensors" is actually a wideband sensor for monitoring AFR, the kit will tell you in the instructions where to install the sensor. Not sure if ARH have a bung already for this since ARH typically cheaps out on features yet still charges the same price. (My Kooks has the bung and fit perfect.)

yeah i apologize... i meant the rears get tuned out, and the factory ones i assume need to go in the forward location.... then for monitoring i can hook up my WB to one of the rears....
