Here's a sketch of the oil's routing through the head. The joint between the head and the cam carriers is not shown. In real life, there are hollow dowel pins at the front of the head that pilot into the bottom of the cam carriers... one pin per cam carrier. They're hollow because they're also the oil passages that flow oil to the cam's front bearing journal.
