Rough idling in startups and cold. (Injectors 7 ,8)

Whats up Folks , im experiencing a rough idle at startups specially in cold weather , no codes but if feels like the car has a Cam and missfire and once is warmed up everything is normal, so I read a couple of threads from guys that replaced injectors 7 and 8 and im planning in doing the same thing since im replacing my IM for a LT2 IM. Couple of questions:
1: does anyone has the correct part number of the injectors , 16SS.
2: Can I reuse the orings of the other injectors ? Just spraying some lubricant before removing the rail to prevent damaging the orings.
3: Something else to look for while doing the procedure .
Thanks !

What makes you think those injectors are bad?

If it's not throwing codes and the idle is only slightly rough (a couple of misses here and there) It's probably fine. Mine does it too ever since I bought mine a year ago. Another one I test drove also did it. I think these cars are just tuned to the edge during cold start in order to meet emissions standards. Also, the injectors fire two pulses during cold start instead of one so I think that contributes to the slightly rough idle on cold starts. I could be wrong but I just feel if there are problems with our injectors it would show a code.
