Sorry incorrect. Of COURSE the coolant is in the head........he's speculating on whether it will "live" OK with the intake. Unlike blocking the exhaust crossover, "if it seeps" a little it will NOT be OK in this case

I don't see it being any different to the water jacket that goes into front of the manifold, and I have never seen or heard of a failure in this area.
