Injector ID?!?!?!?!

Alright... Ive come to you guys in hopes that you can help me with this. I have a Turbo Eagle Talon and im upgrading the injectors. I found these ones on ebay and for as cheap as they were for 550's (usually like 200-250 for our cars) I jumped on it. Now the question is are these really 550's? The guy doesnt know and ive searched and cant figure it out. If you guys would let me know that would be great. Thanks Alot.
P.S. Heres the link

looks like you've made a good deal

Hey guys thanks alot... but now im confused. The injectors look red yet the year is an 85? Look at that chart. There are no red injectors made in for the 85's... just the orange... Maybe its me but I think they look red. Can anyone confirm this... Thanks again.
