Heater core flow?

Well I live in Mississippi and it's smokin hot here these days. But I still love cruisin in my K5... no top, no a/c & all. However, even with the heater off it still blows some hot air out the vents. I had a Chevelle that did the same thing & my Daddy installed a inline shutoff valve in the hose going to the heater core. So I thought I would do the same thing on this "Bucket of Bolts". But I can't remember if he put it in the top or bottom hose of the core. Which direction does the water flow through the core - in the top then out the bottom OR in the bottom & out the top?
