The Ford Racing 44lbs injectors work very well. They are a 4-hole nozzle design for better atomization. I have a couple of spare sets with a few hours on them, if you want to save $.
Turns out the ones i have are not the 44lbs ones. My apology. After looking at them, I now recall I ordered the wrong ones (24lbs) initially and had to reorder the 44lbs ones.
