HELP!!! COOLANT WATERFALL!!

Guys check it out.....see the hole by #8 runner? IT has to be covered by gasket unless its a port for water heating something.....?

<<EDIT>> That hole sure is there, BUT it does not enter water port, its between the bolt hole and the water port window so your gasket just didnt seal it. Its a blind hole with no matching head passage. Just collects dust with a normal gasket.
