Not to argue with you for the sake of arguing (really sorry it's not an important thing to debate anyways) but it will work. Just won't be optimal if he has mix match injectors. The pop pressure is the same, just a slightly different spray. If I recall the newer 60x nozzles have an early mist followed by the main charge. I could be wrong about that but I think that's what they did differently for a smoother idle. Something different in the nozzle near the pintle and it's a very slight difference, that I am sure of.
