Probably a completely different animal, but when I had blown head gaskets on my 6.2 diesel, it would blow coolant out of the radiator when i revved the motor with the cap off. Lots of big bubbles just idling. If you're only seeing a few small bubbles & the engine doesn't have much run time, I'd caulk it up to air in the cooling system - it can take quite a while for all of it to purge.
