Looking on Jame's Dean's spreadsheet program, there's a subtle difference right in the low end, with the E being richer than the F, but not very much. There appears to be little difference in all the NOZ series.
hmmm, didn't think to look on james's spread sheet, maybe my info is incorrect. i based it on my experience with going from an nozh to the nozg. i had my bike ported, & it had a flat spot in the power right where it transitioned from the needle to the main. asked an expert, he said to go to the nozg, it was richer there. did that, problem solved. so i presumed from that that the e would be richer at the top than than the f. sorry if i am incorrect.
mweissen nailed it. NOZ's are the same except for the initial part of the taper.
The effect a slightly richer straight section can have on transitional throttle response is pretty surprising if the the throttle is opened from near closed to near full open. It's easy to make the mistake when you jetting by feel.
The JDjetting guide is very helpful and inexpensive (buzz marketing)
