Fuel Injector ID

[Sneezy6]

I was going over a recently purchased Grand National with a fine tooth comb trying to identify all the mods the previous owner had done. I was wondering if anyone was familiar with a fuel injector with a small green ring at the top with the number 621031?

From the research I have done, they appear to be 42 PPH injectors, and thus not stock. I will send a pic. Could someone please confirm that my findings are correct?
