Valve job isn't too bad. Just insist that that ture OEM guides are used, and they are left alone unless the valve can't be insterted -- no reaming for "clearance" -- make sure the exhaust guides are the original bronze ones.

Removal isn't too bad -- there are a couple or three screws in the chain case that must be removed in order to get the head off, they aren't very obvious.

When you put it back together, you can set the inital valve clearance on the bench, then pull the follower towers back off (you have to -- the head bolts are underneath!) -- valves will still be adjusted when you re-install the towers.

You will have to check the injection timing -- no was to tell if the chain jumped on the cam sprocket or crank sprocket (mostly likely the cam, but?)
