in order of taking things off, here's what you will need to do.
breather cover and valve adjustment covers. this is easy.
valve head cover (or rocker assembly). carefully follow the torque sequence to remove this without warping. make a quick cardboard template and put the bolts to keep the bolts in proper sequence. some have copper washers.
remove cam shaft and sprocket do not drop the chain down the tunnel!!!!
head. under the rubber sealing puck are the headbolts, as well as the few that can be seen. make sure to clean around them, and use a bit of deep creep to help removing them. spray it around the bolt head, and also anywhere you can see the bolt running through the head. you'll need a deep socket extension here to remove them. remove them in proper torque sequence, and again make a template to store the bolts.
cylinder jugs debatable whether or not you'll need to remove this, however, you will have disturbed the base gasket (between the jugs and the cases) so replace it. you'll also install new oil galley o-rings. any ring or piston problems will be evident. it's also miles easier to replace the tensioner.
you'll need a large socket (23mm?) to spin the crakshaft to work the pistons out
the tensioner is tricky to insert properly...,it has to fit into a little slot at the bottom of the cam chain tunnel. the correct installation can be verified with a flashlight through the oil pan.
something i learned during my last rebuild was that using a tap and die set to chase every hole and clean the threads of ever bolt helps keep reassembly smooth and keep you breathing easy.
it seems like a lot, but it's not. take pictures, bag and label everything!!!! ask questions here. we can walk you through reassembly, and the manual is pretty helpful, though members here have posted lots of pictures of what everything looks like.
good luck!
