They've got to face some direction. West is a direction.
From what I can tell, there's a bit of a bias towards an east/west orientation for graves just because the sun rises in the east and sets in the west, so in many places it was common to bury people so that should they wake up some morning (nobody ever said customs had to make sense) they'd be facing the rising sun.
Headstones are usually placed at the head of the body (hence the name). That means, at least by my definition of "facing", they'd be facing east, not west.
