Once the head is off, those sleeves are only held in place by three rubber o-rings on the bottom, and whatever crud is in the jacket that contributes to "gluing" them in place. Look back thru previous posts on sleeve removal, there are lots of them. The sleeves have to be pushed/pulled up, out the top of the block, they can be removed with the crankshaft in, or out. Most guys either push the sleeves out from the bottom using a jack, or press, or beat them out with a heavy mallet on a hardwood block, or they make a puller to pull them from the top. Either way, you will probably want a piece of sturdy metal plate, maybe 5/16" thick or better, cut to the same O.D. as the bottom of the sleeve. Works best if that piece of metal plate has a lip on it so it doesn't slide around on the bottom of the sleeve. Use that piece of metal to push or pull the sleeves. I used the puller method, got the idea from this post, used a piece of 4" metal pipe, just longer than the sleeve, piece of metal across the top of the pipe, piece of metal on the bottom of the sleeve, some 1/2 " all-thread down thru the whole thing. Gave it a turn with a wrench, took a sip of beer, gave it another twist, another sip... Once the initial seal is broken, the sleeve pretty much just slides out.
Clean everything real real real good, and push the new sleeves, with new O-rings, right in. They go in real easy, I pushed mine in by hand and tapped them a few times with a rubber mallet to make sure they were seated all the way down.
I spent more time cleaning and scrubbing the block than I did actually installing new sleeves.good luck
