I've got the same heads and was told they are 118cc but I have never checked.

They are 116 to 118 cc. If they've had big valves installed the right way, they'll often be between 112 and 114 cc. If they've been milled, they will be lower. You cannot flat mill those heads more than about 0.030" without hitting the intake valve seat, by the way.
