Thats sucks man, head removal will be my next step and see if you can try and punch it out thru the back. Hot tanking the head could help with the removal process.

If I swap head with another one does it matter that this motor is a early 94.5 motor and has two less holes on the intake plenums and other motors I've got are later model heads

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

They will work exept the for the 8 bolt to 10 bolt difference, you will need intake plenum from that head.
