I've changed the plugs on an M112 twice and I can tell you its a non-trivial job. That said 3 hours is a bit much, but if you ever managed to cross thread a plug on this baby you would be screwed - it would be almost impossible to get a heli-coil in place without removing the head.
As I recall it took me over an hour to RR the plugs.
