Hi Ago, welcome and sorry about the issue. There's god news though. Since the rockers are simply a platform for the valves, there's no bearing on how they affect measurement. Once you have them back in, then you will need to do a valve tolerance check. If you find some out of spec, find the ones that are loose and swap with the shims that are found to be tight in other valves.
Just be careful in knowing what part of the valve is tight, of course, whether it be the opener or closer.
Also, the best insurance on keeping a tight ship in your valve train is the use of MBP collets. The best $120 usd you will spend on that bike. They will lock in the valves so they won't loose their tolerance. I didn't have to do a valve adjustment for about 17k miles on my track bikes.
