Coolant Leak 72 350 engine

[brown7373]

I am installing a 350/290 crate engine. Pretty much everything is together and I was filling it with coolant, when I saw coolant laying on the right side intake to head. Everything is stock. I used the stock 4 BBL intake with the Fel-Pro gaskets and used silicone at the front and rear of the intake and around the water passages.

It looks like the leak is at the front 2 intake bolts or the intake water passage. The bolts don't appear to go into the water passage, but it appears to be leaking around the water passage or from those bolts. Any ideas on what I should do?

The engine has NOT been fired. This happened while filling the engine and radiator.
