Ah! Glad to hear that. Mine was over-flowing, due to the pressure cap (on the black surge tank) leaking. A new cap fixed that problem of coolant not being drawn back into the system as the block cooled.
My 90 doesn't have a gasket (on the over-flow cap), but I fill the over flow tank to the "COLD" mark (on the attached dipstick) when the motor is cold (with the pressure reservoir filled completely). The level when hot never sees the coolant go over the HOT level in the tank, w/o something being amiss. 
Ami's 91 Z apparently has a "selfee" paper gasket, cut from gasket paper, but is otherwise identical.
