head gasket ?????

[gt6878e]

Hi all, after a little run out today i started to lean off my carbs as the car is running a bit rich, but, while i was doing this i noticed some small bubbles blowing from between my head gasket. Only on the carb side.  No loss of power, no loss in water or oil mixing with water or anything.
Question is do you rekon my gasket is on the way out???

Im no expert but I would have thought so, spend a few hours taking the head of and replace the gasket before it gets worse :-)
