Injector cups were know for leaking and cracking etc on the 7.3, 6.0 is a different animal. The cups are stainless and very robust, every one I ever had on a 6.0 was a cracked head. On the 7.3 the top of the cup were it seals to the head is interesected in the fuel area on the injector orings, 6.0 the top of cup is below the sealing area. Its possible for the lower oring and the cup to fail, but not likely.
You'll need the injectors to seal of the fuel rail in order to test the integrity of the head, they are needed to plug the hole.
