On a cold engine remove the rad cap and make sure the rad is full to the top. Attatch a piece of hose to the overflow spigot (beside the rad cap) run that hose into a big glass jar 1/2 full of coolant making sure the hose remains below the water level. Fire it up and look for bubbles during/after the engine warms up, if you see a steady stream of bubbles when warm then it is best to assume you have "troubles".
If the heater core was leaking you should:
1) be able to smell it inside the car
2) should see it on the windshield on "defrost"
3) see a stain in the carpet
If the headgaskets are leaking bad I would expect to see tank leakage if the car has an alumnium rad (left side top). These cars are mostly old enough now that the copper rads (original) are beat.
Check the hole you can see in the water pump (top covering the shaft, behind the belt pully) you so not want to see water here.
If you pull the spark plugs you will see which cylinders are getting water.

Burning coolant (could also be intake mani gaskets though)
Mix of coolant and oil in either the oil pan or radiator
Bubbling coming out of the reserve.
