Did a little more searching, found all the info I needed.
789's are a good upgrade. 4 hole, better spray pattern, etc.
It was mentioned that they have an angled spray pattern, but from looking at them, I'm not sure how that would be unless they spray out of the holes at an angle.
Several of reports with others about them being easy to find and a great plug N play replacement. Gonna get'm swapped out as soon as I get some time and better weather.
789 injectors,,,,, I'm gonna use'm. I'll add info on them in my build thread when I get a chance.
