Check the Probst description of the head's operation.  I suspect that, during 
initial assembly, the individual port adjusters (Allen screws, visible on the 
top of the head) are wound in individually.  The head is probably supplied with 
something like distlled water at the appropriate pressure (just below normal 
fuel system pressure) and each adjuster is wound in until the flow _just_ stops 
for that port.  If you switch around the small components associated with each 
port, or switch the diaphragm, I think you will have to set up the ports like 
this.  I have a head lined up to check this out sometime in the next couple of 
weeks.
