Coolant leak on W2 heads

Latest update,
I took my engine builders advice and heat cycled the engine a couple of times, then took for a trip on the highway. This was last evening, upon return home, there was sweat at head gasket area that I wiped clean. Today it is absolutely clean and dry. So far so good. Fingers crossed!

I did pull all plugs and cranked over prior to firing. Was no fluid, radiator level has not changed. In total, the leakage would not have been more than a thimble full, if that.
