It's not very hard at all. Just make sure everything is at TDC before you go putting the timing belt on.
Pull the valve cover off.
Set TDC, and pull timing belt off cam gear (you will need to loosen belt to do this)
Unbolt intake mani and exhast mani/header
drain coolant and remove radiator hoses
make sure everything is unbolted/unplugged from head
take out headbolts from the inside moving out
Pull off the head, check for any signs of warping on both head and block. Replace gasket
If head is warped, you'll need to get it milled.
Clean up head and block, bolt it back together using the torque wrench. Inside moving out, 14lb, 26lb, and finish with 46lb.
Put hoses back on, bolt on intake and exhast mani, bolt on distributor, bolt on valve cover, replug everything, fill coolant back up.
Make sure everything is still at TDC, put on and tighten timing belt.
Recheck everything. Timing will probaby be off, so it will need to be fixed but the car will still be perfectly drivable.
It's really just a matter of pulling everything off the head, removing the head, replacing the head, and putting everything back on.
Just did it recently, took me the good part of a morning.
