Question about fuel injector nozzels

I've got an 88 Toyota pickup and I bought new injectors for it but 2 of them have a slightly different nozzle, it's a tiny bit longer and slimmer and the two holes that spray fuel are much larger than the other ones, which match the original ones I took off. My question is do the hole size matter? Is it going to spray more fuel into the cylinders than the other 2 or is the pressure regulated so they all spray the same amount?
