Engine/Transmission (1998.5 - 2002) How many injector holes???

[justinp20012500]

I just pulled the head off of a 2002 HO cummins and noticed that the pistons had 7 spray marks instead of 6??? Does the stock HO injectors have 7 holes instead of 6??? Or whats the difference? Or what injectors do I have?? Is there a way to tell?

24 valve engines 1998. 5-2002 have 7 holes in the tip. HO injectors are small. Not an upgrade for the other 24 valves.

If I remember right, my stockers had 5 holes. The 275's and the extrude honed injectors that are based on 275's have 7 holes.
