injector cups stuck in head

Can't punch through from the other side, just the nozzle hole goes all the way through, no part of the sleeve to push on.
I have run into this before.
Very carefully take a proper size chisel and try to score the sleeve across, like at 12:00 and 6:00. VERY carefully. Did I mention to be VERY CAREFUL doing this? You don't want to knick the surface of the bore AT ALL. If you do the head is junk. Don't ask me how I know.
Then, use a propane torch to heat it up to break the bond with the retaining compound. With a long screw driver, long pliers, etc, or whatever works try and pry the pieces up so that the pliers will grab them. Like put the screw driver in the chiseled slot and twist and turn sort of thing.
If you happen to have any of the sides of the sleeves left, try to pry a section of it away from the side CAREFULLY, and using long pliers try to grab that part of the sleeve after heating, before using the chisel. You need to be VERY careful using the chisel. Not sure if I mentioned that.
There is no easy way to do it, it will suck no matter what. But it's worth a shot before replacing the head.

I'm definitely still gonna try to get them out but I'm pulling head because the second that broke is passenger back one and I honestly don't see a good way to get at that one almost have the head ready to come off of it doesn't come without damage I'm pulling heads off my old motor to have them checked and go from there

OKAY another question can I reuse my stock headbolts I was hoping to not half to mess with heads till I could put studs in but to late for that should I go ahead and try to get studs now or should I just wait plane is for stage twos and s369 eventually right now I'm running 175s I got a fair deal on but I'm just building a reliable tow rig I may just stay as I am with stock nozzles do you guys think studs are necessary thanks again
