First off, thanks for all of your help.
As far as the above is concerned, here is what I have surmized:

Yes they are stuck. Engine was running (with a loud clanking noise) a
few weeks ago.
Yes I tried oiling them, penetrating fluid. I was able to get the others
either using the pushrod suction method, or sticking my finger into the
hole on top
and pulling. It works well, until the bottom part of the tappet starts
coming to the
top of the bore. Then it binds and the finger/friction is not enough to
I'll probably just wait until I get the bottom end off to get these out.
2. Distributor drive spindle.
I was initially afraid of getting the big hammer out, but sounds like from
that persuading it is ok.
3. Cam removal:
At this point I'm not sure if the oil gear is required to be removed on
I think the Haynes manual and the Bently manual give conflicting info.
with the tappets still in there, I'm not sure its a good idea to leave them
in the cam area w/o the camshaft, so I may leave it in for now.
4. Lifting engine by head bolt threads.
I was planning on making some braces to go across the engine w/ holes
in them into which to put bolts which would attach to the engine. The
of the hoist would attach to the braces. Sounds like this is an ok plan.
Thanks for all of your help.
I'll keep you updated (read: asking for more help in the future.)
