My gut instinct says to drain the oil and once it cools down retorque the intake bolts, top it back off with coolant, and put the drain plug back in. Let it sit overnight (or longer) to see if it loses any coolant and check what comes out of the pan afterwards.

Great advice. Thanks, everyone! I think I will do this for peace of mind and get a better idea of what's really going on with it. I had planned to just "burp" the radiator and see if that was it but this is probably better advice for good measure. Offenhauser intakes have little info (this is first vehicle I've owned with one) - 20ft lbs sound about right for the intake bolts?
