The same guy that is selling a set of Z06 sway bars also has some Z06 injectors that he is getting rid of also. If I can get these for a good price would they be worth putting in my '05 LS2?

The fuel injectors that are in your car now are plenty enough. If they were given too you then that is one thing. But to pay for something that you don't need? Save your $$ for something else.

I don't believe the would work anyway, I knew I had seen a comparison photo somewhere, so a few Google searches and here you go:
