The vacuum lines should go to the front of the distributor via the vacuum tree on the thermostat housing.
The tree has 3 fittings - the middle one goes to the advance on the distributor, I think that the top one to the ported vacuum from the carb (you'll need to find it on this carb) and the bottom one to manifold vacuum (or it could be the other way around for these two).
Anyway, the timing is set with vacuum blocked off, then connect the hoses and the timing at idle gets retarded slightly and the idle speed slows slightly. If the car idles too long, it overheats and the vacuum switch routes pure manifold vacuum through, advances the idle speed and cools the engine with more fan drawn air.
Think you need to check the angle of the carb top with a known good one - then statrt replacing stuff with OEM ford to get it right (or just make a angled spacer)
