Comes up the pushrods and out every other orifice in the head back to the sump. Look at the bottom of a head and you'll see

I couldn't remember for certain so I just checked out some old 241 heads I have under the bench, they drain back through the outer two head bolt castings as well, not just the middle three. Some oil would flow back through the pushrod holes but the majority should be through the head bolt areas.
