will they fit on standard fuel rail?
Honestly, go with the 1000cc. You're returnless, and you don't want to have the issue of getting new injectors again. I made over 400whp turbocharged with SFI 1000cc injectors and a walbro 255, without a return. Now I have a bigger fuel pump and a full return setup with a -6 feed. The 1000cc will also allow you to run e85, which you'll love if you have it available by you.
