Default coolant bubbles

Ive been worrying about the head gasket lately after the heads/cam job. Today I ran it for a while with the radiator cap off, and seen lots of little bubbles coming up through the radiator. The car runs fine, coolant does not overflow and does not go down, sparkplug was dry, oil is not milky anymore, no white smoke out of the exhaust. is the system just working all the bubbles out of it or could it be a problem, you guys think im just scaring myself??

well my car is currently torn apart because i had the same problem im pretty sure my problem is a headgasket it smoked out the exhaust and smelled like coolant. I also noticed bubbles with the cap off after much bleeding and i didn't have any milkshaking of the oil either it was so bad that after a few days of sitting it would be hard to start cause enough coolant had made its way into the combustion chamber and was attempting to hydrolock. cross your fingers bud i would hate to see another LT1 with a bad head gasket.
