Fuel injector identification

[BLOHS7844]

I have 4 blue top fuel injectors. All 4 are inp-009. 3 of them have 914 on the same side as the inp-009 and 1 of them has 898 on that side. On the other side all of them say B450L but those 3 with the 914 had the letter G on that side while the odd one out had the letter M. Is this ok?

They are all 1G blue top 450's, one is probably out of a different year car
