pulled injectors out of my 99 dodge cummins part # says there stock the number of holes on nozzle is 7 holes i'm wondering if anyone knows how many holes are actually in stock nozzles on the set I pulled it looks like the nozzles have been changed due to one having rounded off nuts on injector and the nozzles looked like they have gotten quiet hot they where very discolored like when steel gets heated up

 

7 is correct. You might want to get them pop tested.
