If the ECU temp sensor at the back of the head doesn't get a signal due to an air pocket, you will get an rhythmic idle like a sine wave, up to roughly 2500rpm then back down in a constant pattern. You need to be able to get the engine warm with the radiator cap off until the thermostat opens, at that point you should see coolant flow when you look in the radiator. Keep giving the rad hoses a good squeeze until you get no more air bubbles. Once that is sorted it should idle nicely.The bolt on the side is simply a block drain.
If it simply idles like a pig, this isn't your (only) problem. Then it could be a few things, cam timing, cam timing, did I say cam timing? You won't get your static distributor timing right if the cam timing is off, everything will be off. Then of course there are simple vacuum leaks etc, etc, etc.
