Terry,

I forgot about the loop (about 3/8" dia. or so) from the upper radiator hose through the throttle body and then back to the radiator (I think). I disconnected this loop a few years ago on my 94 Z28 by using a upper radiator hose from a later model Z28 and blocking off the other end of the 3/8" hose.

I think the flow from the steam vent (rear of heads) goes to the throttle body and then to the plastic make-up reservoir on the B & D-bodies, but I would have to look in the FSM to be sure. I will do that if it is valuable information to you.
