The cylinder head contains the valves which regulate the intake and exhaust flow through each cylinder. Reliable flow confinements are needed for each valve for 1-D engine simulation software. The head needs a custom 67 bore adaptor and a device for mm controlling the valve lift. The cylinder head needs to be measured under both negative and positive pressure differential. Figure A4.
