I guess that answered my question;
I have the 'water flowing thru the tank with radiator cap on the tank'.
I did it to make sure all air is continuously removed from the system. Any 
bubbles would go to the top of the thermostat housing and flow to the top of 
the tank. The line from the bottom of the tank goes to the water pump 
suction to assure that the engine stays full. 
When filling the system for the first time, the water enters the tank thru 
the cap, and flows out into the engine thru the bottom 5/16ths hose, air 
departs thru the upper hose until the system is full.
When the engine is started, any trapped air in the forward part of the 
engine gets pushed thru the turbo bearing housing cooling line back to the water 
pump suction, where it rises thru the vent hole in the pump housing to the 
top, then is pushed to the head tank. Effective, heavy.
I see now that I can put the fill cap on the thermostat housing, and run a 
hose to the burp tank bottom. Skip the header tank and remove a few pounds 
from the fire wall. 
Put a tee in the fwd 'vent' that sends cooling water thru the turbo, and 
open it when filling the system to purge air. Connect the cooling water 
pressure sensor here. 
Small remaining bubbles would acumulate in the thermostat housing/filler 
neck where they would stay until enough system expansion pushed them out the 
cap to the burp can. Upon cooling, system vacuum pulls water from the bottom 
of the burp can, until no air remains in the engine...like the car.
DOH! And I spent so much time and effort on the old system.
