Just frount O2s. The rear O2s can be deleted out.
I think the rears ( after cat.) are just to make shure the cats are working right.
The front o2s are used for tuning and what your engine uses to adjust the fueling tables rears just basically say "the cats are still here" just get some o2 bung plugs and plug the rears and turn the o2 code off with the tune. I am going with the same setup on my 418 should work out pretty nice for you.
