It seems to me that the Delphi #FJ10062 has 4 "spray holes", while the #25317628 has 2?

Hey guys I have a question for all of you. I have a 2003 Silverado 1500 that ORIGINALLY had a 4.8l in it. As some of you know, I had a 6.0 swap done on it 2 or so years ago. Recently, I got the dreaded P0300 code. After all of my testing, I have come to the conclusion I have a bad fuel injector. So here's my question. I removed one of the fuel injectors, which is a Delphi #25317628. After shopping for a new one, I have been given three part numbers and can't make sense of them. I am told a AC Delco OEM injector is #17113698. I have also been told that this is the SAME injector as a #25317628. So I am leaning towards this purchase. However, can anybody tell me what a #FJ10062 is?! Given that my injectors are more then likely from my 4.8l, I was considering swapping them all to injectors for a 6.0l. But from my research, the 4.8/5.3/6.0 all use the same injectors? Thanks in advance!

There is about 12k invested, plus another 6k for the new engine I'm putting into it this week.
