Adam,
The TD head is held on by 10 nuts on ten studs. To remove the head, you have
to undo these nuts, disconnect the manifolds and the upper hose. You must
also undo the three hollow bolts that hold the side cover on and pry it away
from the head as this cover's gasket is pressed against the lower edge of
the head. It's not essential to remove the rocker assembly but, if you
don't, then the pushrods will come up with the head and make it more awkward
to handle.
If you've done all those things and the head still doesn't budge, then the
culprit is possibly corrosion between the studs and the holes in the head.
Spray liberal quantities of something like PB Blaster down the stud holes
and let it sit for a while, then try again. 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............
