I started on car this week and now have both heads removed (engine in car)
damage is 16 bent valves ,other 8 look ok but will check more thoroughly when I dismantle them next week.
Only real problems were removing thermostat housing which was properly stuck on (I now need a new one)
and removing power steering pump which was a real pain ,not a lot of room to move in there !
Pistons do have marks where valves got intimate but otherwise ok
Not sure whether to replace water pump though as been reading on forum and they don't seem to be a problem on these engines.
More updates soon
