Hole count doesn’t matter too much, spray angle does.
Is your truck an 04 or 04.5?
03-04 had 8 holes and 04.5-07 had 5.
03-04 spray angle can be used in 04.5-07, but 04.5-07 can’t be used in 03-04. I personally prefer to match spray angle to the pistons, but lots of good reports of 03-04 in 04.5-07 5.9’s.
What are the replacement injectors?
