1. A method for controlling the volume of the chambers in a cylinder head of an engine in an in-line manufacturing process, said method comprising:

  • electro-optically measuring, in line, the location of a plurality of points in the cylinder chamber as referenced to the face of the cylinder head, for each of the cylinder chambers of the cylinder head of the engine;

    transmitting, in electrical form, the results produced by the electro-optical measuring step for each cylinder chamber, to computing means;

    computing, using the computing means, the approximate volume of each chamber from said point locations;

    comparing, using said computing means, the computed volumes of the cylinder chambers; and

    selectively removing material from portions of the cylinder head defining the cylinder chambers, in line, as required in accordance with said comparing step, so that all of said cylinder chambers have the same nominal volume.
