Basically, if you're changing up to 2 injectors, the class must be the same or different by a maximum of 1.
E.g.
Class 1 is compatible with a class 1 and 2 system
Class 2 is compatible with a class 1, 2 and 3 system
Class 3 is compatible with a class 2 and 3 system
Bizarrely, there is also a class 4 which is compatible with all systems.
It's also important that the ECM is programmed to the same class of injectors that are fitted so if there's been a wholesale change of injector class previously you need to check using Dice and Vida what class the ECM is programmed to.
