Did the white smoke, or steam have that sickeningly sweet smell of antifreeze? Did you get a taste, of the fluid? It used to all taste sweet, if it was AF, but now they put bitterant in it to keep idiots from drinking it!
Inspect webs between cyl's for cracks, if you have no AF in the crankcase, don't bother with the sleeves. Might as well check the head for warp, if you have it off, too. Oh, and lap the valves, and check the valves, and guides, when you have it out.
If the pan gasket ain't leakin, leave it alone, till you get into the motor. JMHO
