<If this doesn't work, use a stud extractor (or double-nut the studs) and
remove as many of them as you can. This allows you to wriggle the head around
more, breaking any residual seal with the head gasket. If all the studs come
out, you can also use "percussive persuasion" to knock the head sideways to
get it off the block............>>
If all else fails, you can also put the spark plugs back in and hit the
starter - the compression with all the valves closed may move the head, but
try Lawrie's penetrating oil first.
Worst case of stuck head I ever had was a Triumph Mayflower, which had an
aluminum flat head that corroded to the steel studs. The only way to get it
apart was to make up a hollow saw that went over each stud and, used in a
drill, cut away a thin layer of aluminum around each stud. Took forever!
