The 8N has thin "dry" sleeves that fit in a semi finished bore, and are not exposed to coolant to rust them in place.. The A has "wet" sleeves, and two packings or "o" rings at the bottom that ARE exposed to coolant, which usually seeps into the grooves, and rusts the whole thing tight. I have seen blocks with part of the "o" ring land ripped out by the rusty sleeve being pressed out. It sure could not hurt to weld a series of beads inside the sleeve, especially in the bottom 2 inches, where they are stuck the worst, and the place the block, well supported, upside down in a press and push them out with a thick steel place machined to closly fit the bottom (top in this position) of the sleeve. This is the type of job perhaps best left to someone with the proper equipment, if you do not have access to it, as a fee paid to a good engine man to remove the sleeves would probably be a lot more reasonable than a replacement block! Using a sleeve puller which presses down on the top of the block could possibly break the upper deck if the load is not spred over a wide enough area.
