Iso modding

Okay so i was wondering if there were iso mods for Black ops 2 if so then that would be great and also black ops 1 because no one has really tried to see if there are actually iso mods for them and one more thing i know mw2 has them but where can i find a clean iso? Thank You :smile:

ISO files may be found at www.xbox360iso.com

You can do solo mods for all of those games, but not online mods last time I checked.
Anyone can feel free to correct me though.
