My front cylinders get more air from the blower, so I run bigger fuel nozzles in the front cylinders than the back ones. I fine tune by EGT (have a sensor on every cylinder). I balance the temps by cyinder and that's my final tune. My hat nozzles are all the same, but my port nozzles run bigger in the front, since the opening on the bottom of the blower is offset to the front. It's not a big difference between cylinders, though.
