Prop Valves

I've been trying to figure out what the difference is between the prop valve in a 2000 Si w/ABS and a 2000 SiR. As far as I know the master cylinders are the same but could someone clear it up for me?

SiR has rear discs so that PV will have more rear bias than the Si one

one is 3030 and the other is 4040.

match it to what brakes you have in the rear, if you have drums, get the Si, if you have disks get the SIR one.

Just for the sake of cheapness, will the Si prop valve and mc work if I pull an SiR rear brake swap? What will deteriorate regarding the brakes, pedal pressure or balance?
