Try retorqing the intake bolts and see if that stops it before trying anything else. The gaskets may have settled, allowing the bolts to loosen up. The reason I asked about what engine it was is starting in 1980, the lower head bolts on 302's were drilled all th eway into the coolant jackets, these lower bolts need thread sealer on them, without it they will leak coolant, but it usually leaks under the bolt heads, not the gasket.
good call there and I've seen more than a few of these motors with long term leaks in the same area. And one of the best sealants that you can buy.. and included in many of the recipe's of the more expensive factory/industrial sealers.. is called sodium silicate. All the old timers used to call it "liquid glass". I've used it for temp fixs on cracked heads and have known others who've sealed cracked blocks with the stuff as well. You can get it at walgreens in quarts/half gallons(or maybe it was liters). The stuff is awesome and you can even combine it with some aluminum based stopleak powder to stop major gap leaks. However, you will need to completely flush the coolant out and go straight water to get the best benefit. Which I would strongly recommend anyways if the severity is anywhere near what you describe here. Not many low budget time saving shortcuts will help you at this point and you need to do the extra work if you really want to save the bigger cash repair for later on. Might not be 100%.. but it will get you down the road with only an old antifreeze bottle full of water in the trunk needed for ocassional top offs in the short term. I also have a buddy who just used this stuff about 3 months ago(at least I'm pretty sure this is the same stuff because it was expensive as hell.. but I can check later this evening if need be to make sure) on his older Northstar caddy which popped a head gasket. Must work pretty well because he still drives the snot out of that thing on the highway and it hasn't started to leak again. His motor would be a bear for us to work on though.. and yours is a kitten with a much cheaper repair if going the full way to do it right. I don't think it would be worth the cash and time savings in you situation.
