leaking coolant 1985 Buick Riviera 307 5.0 V8

I have coolant leaking from the top right hand side above the water pump. Its not the water pump, but seems to be from the engine. What are the possibilities here ?

Intakes at both corners, very common on the 307.

Thanks. Is there any quick way to fix this problem, or is it going to be a long job ? Do you happen to know the process and how to determine if it is the intake gasket ?
