Perry,

I presume you did not pull the engine to pull the head.  You do not say 
whether you replaced the chains and sprockets.  If you did, I presume you 
have lined up the timing marks on the sprockets as shown in the manual.

1.  Put the head on with or without the manifolds, as you prefer.  I have 
always pulled the manifolds before removing the head when doing head work 
with the engine in the car, but do whichever works well for you.  It will be 
easier to get at the inner studs/nuts on Number 4 exhaust port with the head 
off the car.

2.  No need to pull the engine.

3.  Follow the alignment diagram on Page 23 of the shop manual, and you 
won't go wrong.  (Again, you didn't say whether you replaced the chains and 
sprockets.  If you did not, then I presume you preserved the position of the 
camshaft sprocket with the upper chain.  If you lose that relationship, I 
know no way to correct things short of removing the oil pan, water pump and 
timing cover to make sure all alignment marks are in the correct position.)

Sorry I could not be more help with Point 3.  Provide more detail on what 
has been done to the engine, and how the timing component relationships have 
bee maintained or re-established, and perhaps I can say something further.

Gary
