Default Where does this hole lead to?

I removed my valve cover and noticed these 4 holes next to the valve cover bolts. I am curious to know where this hole under the valve cover leads to. It looks like an oil drain hole? Does it go straight to the oil pan? Any info on this hole would be much appreciated. Thanks

It is a passage through the head and block leading down into the crankcase to be recirculated and filtered by the oil pump.
