As far as I know the RX rods and pistons have never been seen by anyone. R&R made my forged rods. Both Wiseco and Diamond made me 10:1 CR forged pistons. Wiseco also has a hardended ring package to work with their pistons. It isn't cheap.
I don't think you will have problems with the Rods at 7psi and a 65 shot, but the pistons probably need to get swapped out. I used my stock rods up until about 600 RWHP/RWTQ and then they failed in a fabulous manner. However I'm all boost and no spray with a 4000 stall so I may be hitting it harder than you will on more boost and spray. Only you can make the call, but if I were you I would do both rods and pistons while you are in there.
