Having faced the same trouble last year what finally did it for me was a
technique similar to the one Daryl describes below. Only difference being
instead of chisels wedged in those bosses I used a large Craftsman
screwdriver. Make sure it is a Craftsman because if you destroy the
screwdriver (like I did) that lifetime guarantee gets you a new one on your
next trip to Sears.
What finally broke things free was the application of heat from a butane
torch. Try to heat just the head near the cylinders. You want to get the
head hotter than the cylinder so the head will expand away from the
cylinder. There is no need to get it very hot at all. Just enough to break
the "weld" that has formed over the years.
Beat on that wedged chisel/screwdriver while the head is hot and things
will come apart with relative ease. Just make VERY sure all combustables
have been cleaned from around the area before applying the torch. If your
level of paranoia is a high as mine have the wife/kid/neighbor standing by
with a fire extinguisher.
Your cylinders may not be stuck half hard as mine were so the torch may not
be needed but if your find your cussing getting loud enough to disturb the
neighbors keep it in mind.
In a way I kind of envy you. Few feelings I have had in my life were as
pleasant and satisfying as the feeling I got when I at last saw daylight
between the head and that &%!@%#^ cylinder!

Alright.Thanks for the advise guys. I'll dig into it again this morning.
I was wondering though, could I use some sort of wd-40 type stuff to help
break them free? Or would that cause a whole mess o problems inside the
block?
Thanks,
Don
