If you got a real good deal on them, you can get the injector threads turned down and rethreaded for first gen size and reset to correct pop pressure. That would probably cost 150 or so, so you would have to get them pretty cheap to make it worth it.
Thanks for the info guys...I've had this thought pop into my head more then once. Just doesn't seem worth it to me...buy the correct ones and be done with it.
