""""I've only done the job once, and I could have comfortably had it done in
a weekend if I didn't have to pull out the cylinders. It was a week before I
got it all back together including running around to the machine shop and
waiting for things I needed.

Good luck! Wes """""

The top of the sleeve have "tabs", they are pry point.

When removing a head it is important to place both pistons at the mid travel
position, not at TDC (To put them at mid travel point, remove both spark
plug and insert something soft to feel the piston position ). This way, you
can get the head out a bit more without the sleeve passing the pistons rings.
More room to see the tabs in question. To separate the sleeve from head use
a pry bar, the round side of the pry bar should be the one touching the head.

On  this picture, you can cleary see 2 tab:

If your working alone, left the head just enough to see the tab and insert a
piece of wood to hold the head in place:

Also, when you have remove all heads bolts, the head will be loose, take an
heavy soft hammer (rubber), bang the head hard on each side, at 90%, the
sleeve will come loose. If not, use the pry bar method.

On this picture, you see all 3 tabs on each sleeve, there is 1 long tab and
2 small one on each sleeve.
