If the sleeve is junk, which obviously it is if you are removing it..........weld a piece of 1" angle iron about 6" long in the sleeve. Weld up both sides with a wire welder. When you turn the block over, the sleeve FALLS out. I personally don't like to heat the block much, unless I am taking ALL the sleeves out. In that case we have an old commercial oven that will hold a block. A few minutes on "BAKE" and they fall out easily.............lol
