indirect engines or even petrol engines are a pain;
with the head on a bench upside down--valves closed and pointing upwards, a pippette is used to measure in amounts of liquid in c.c's until the level of the liquid is level with the cylinder head. the liquid will obviously fill the entire area so thats about the most accurate way---performance heads are also measured this way when larger valves are fitted and combustion chambers enlarged by grinding, as all cylinders must have the same size combustion chambers.
