I believe that any of the stock nozzles are more then capable of flowing what a max 10mm head/rotor can put out. As far as higher pop pressures, I could only assume the higher the pop pressure there might be a very slight decrease in fuel injected per stroke of the plunger. As the pressure rises there is more of a chance of the fuel getting pushed past the control collar and the mating surfaces of the plunger and head itself, it would be very minimal though.
The injectors will remain open as long as it's needed to inject the specific quantity of fuel the IP is suppling, whether it be at 130 bar, 155 bar or 180 bar.
