Coolant leak front passeger side beneath intake. Source?

[Dan R]

There is coolant dribbling down the front left of the engine and running off the frame cross beam.
Is the lower intake gasket the most likely suspect? Could it be a head gasket?
Thanks for the tips.

Where do your eye balls see the leak?

From what I can see it starts at the head gasket, the edge of which is wet. There is no sign of leaking occurring further up. The lower intake is dry. Hard to check the water pump flange completely. I didn't think head gaskets would leak externally. Seems they do?
