If you have a manual (and a torque wrench) it isn't a difficult job at all. The amount of time is dependant on how detailed you want to be when reassembling (cleaning and painting). Just replacing the head gasket as quickly as possible (like the shop would do) takes only an hour or three. If they're doing a valve job then that would take longer and justify that cost.
-remove seat and gastank
-disconnect negative battery cable
-remove exhaust
-remove carbs
-disconnect sparkplug wires and move out of the way
-remove valve cover (15 bolts, might have to remove the horns)
-loosen the camchain tensioner
-remove camshaft sprockets (align the dots on the cams)
-remove the cam bearing caps
-prevent the camchain from dropping down in the engine (long screwdriver or tie it up)
-remove the camshafts
-remove head nuts
-lift the head off (without breaking any cooling fins)
-clean cylinder and head gasket mating surfaces
-install new headgasket and reassemble in the reverse order.
Of course you can spend countless hours detailing everything while it's apart. That's what I'm in the middle of doing on my LG that is going one step further with a big bore kit.
