I will no doubt show my colors of ignorance here.... but what is the port sticking out of the front-passenger side of the cylinder head? I see it connected to the radiator, is it the coolant entry/exit for the head? sorry, i can't find a convenient pic right now.

 

upper radiator housing?

 

Its the upper radiator housing if its on the pass side of the headcloser to the back. Thats the only real "port" on the head besides the combustion ports.
