Planning on spending at lot of extra time at work? You would need to allocate at least 16 hrs per head. Unless you have seen a Clevo head cut in half you (and I ) wouldn't know how much metal to take out from where. Its easy to hit a water jacket in these things.
When you have finished, a trip to a flow bench would be needed to check flow rates are at least similiar for each port.
By the time you get to your last set of heads you might be getting good at it!
