Here is a link to an Injector calculator. Based on your goals of ~580, I put in what the crank hp is (since that is what you would be using for the formula) once you factor in the generally assumed 15% drivetrain loss (puts you just shy of 670hp), I came out with an estimate of an injector size of 733cc with an 80% duty cycle. I would be willing to say that either 750cc or 800cc injectors would give you a comfortable overhead without being way to big.
--edit--
I should also say that if you go to 85% duty cycles, you could possibly run a 700cc injector.
