Here are what the new alignment marks look like for the cams on the 2010. The letters EX and IN are no longer marked on the cams.
Exhaust Cam (Two small indentations, one is covered by the white paint mark)

The marks are intended to line up with the surface of the head, without the rubber seal for the valve cover in place. I made a small line above the mark on the intake cam that lines up with the edge of the seal, since I left the valve cover seal on the head.
