I had a block years ago with a stuck sleeves...I took the block to a meat locker and rented a space...froze it a few days...brought the sleeve puller with me-put it in the back of the pickup and gave em the works!
all but one came out.
I then got a block of dry ice and left it in the hole till it was good and cold and then that one came out.
These days I don't know if a man can put an engine block in a food locker but you might have luck with the dry ice though...
Good luck!
