Thanks guys I have the injectors out. Now I need to figure out if they are Chinese. I bought them over a year ago I do remember them being in a blue and red AC box. Is there anyway to tell by looking at them? If there I’ll post pictures.

iirc the only way is to pop them apart and see if the nozzles are of what manufacture, but I also wouldn't recommend pulling them apart without a clean room. I would talk to Marty's guy and send them over to him having him fix them up for you. this will eliminate this as the issue.

And that I think is the best option unless @Rockabillyrat Would be willing to take on such a project.
I have nit seen him in the forum for a while, unless I am just missing his presence.

As long as you try to keep dirt and gunk out of them you should be fine. Doesn't necessarily need a "clean room".

Ok guys bear with me I am on Medicare. The injectors are Bosch not AC Delco. I don’t know where I got the blue and red AC Delco box thing. Some of the injectors had yellow dots on them. Doesn’t that usually mean that they were tested. MrMarty51 you said you had Bosch injectors from India that were new. How do you know if they were new? If these are new maybe I should have them tested and balanced but I am a little worried because you had trouble w/ yours. If they’re rebuilt maybe I shouldn’t.
I’m like you and don’t want to take any chances w/ this new motor. I went online and looked for real AC Delco injectors and was overwhelmed trying to find which ones were real AC Delco. Gmparts.com say they have GM original parts. And ACDelco is aftermarket backed by GM. Can only get AC Delco from them
$127. Each. What do you guys think?

Send them someplace to be tested and balanced

Send them in.
Ignore the number on the bodies as the internal is the part that counts. And once you open them up, they need tested to ensure they are sealed.
Either Rockabillyrat or Marty’s place.
