what kind if injectors are these?

[wicked_stenH]

I came across a set of 1st gen injectors for sale local to me, but the guy knows nothing about them. he claims they are larger than stock but has no idea how much/ what size.
the bodys are stamped-
9744
59ps
08708
908

the nozzle is a 5 hole labeled 9754

any idea what they may be or where i could find this info?
i searched and checked the stickies but had no luck
