Question Back of rail can use slightly more fuel?

For my LS2 in the 2000 SS below...

RC engineering cleaned and calibrated my injectors all around 440/min. flow. Unfortunately I damaged two tips. RC happened to have 2 more of the same and shipped me...they flow slightly more @ 442/min..

I was thinking maybe put the higher flow ones at the back of the rails... Maybe there is a slight fuel drop back there? (Because on previous 94 Z blown LT1 engine the #7 and #8 pistonring broke first.

(Also Planning to spray a 150 shot on this N/A all forged engine at some point.)

Or maybe it makes no difference, anyway about to put them all back in and would like your opinion!
THANKS!

If you have known lean cylinders, it doesn't hurt to strategically put a "larger" injector there.
