I am afraid there are no easy way to deliver equal amount of water to each cylinder unless you are in sync with your individual fuel injector that happen to be a multi-point and sequantial type. Even the seqential system doesn't direct the fuel into an open valve. It only happens at low RPM - at high RPM and load, there will be fuel waiting at the closed inlet valve.
If you are going for port injection, there is no point using an atomising jet, I have worked with a few R&D labs - they all use a pencil shape jet, directly aimed at the inlet valve.
If your aim is inlet air cooling + incylinder cooling, it is better to use one single jet after the intercooler and four individual non-atomising jet on each port. You can set the flow ratio between the two.
Water will cool by evaporation until it reaches the saturation point. From that point onwards, no more cooling is expected.
