Head R&R is quite straightforward on these, but you should either take digital photo close-ups or make notes and label wires, vacuum lines, etc. for reassembly. I always think I can trust my memory on jobs like this and I'm always wrong. Read the manual(s), do the whole job first in your head while looking under the hood, and just be very deliberate and thorough during the real thing.

It is critical to totally clean old gasket material off the cylinder deck, and to seal off/protect all openings while doing so, esp. the little hole on the exhaust side of the block which is the oil feed passage to the head. Head fastener torquing procedure is different for different years of these engines - early versions (pre-80?) required a re-torque after some initial run time. A good manual will have an illustration of the different fasteners so you can tell. After reassembly, pour fresh engine oil over the cam lobes and valve buckets until it fills the baffling that was designed into the head to retain oil after shutdown.

Some folks like to use assembly lube on cam lobes when reinstalling a cam shaft, but IMHO this is unnecessary on these engines: relatively low valve spring pressures, an already "broken-in" camshaft, and the puddle of oil it runs in due to the baffling will nicely handle any lubrication issues. Use of assembly lube typically requires an oil and filter change after about 20 minutes of running.
