The marks for cam position are on the camshaft back side, not looking from the front looking at the rear on the camshaft plate with the cutouts , and the cam timing gets set at 40 degrees , note the hash marks are hard to see, but when crank is correctly set , those cam hash marks are level with the surface of the head, those other marks at front are for a new chain installed with copper links to line up to, ie a copper link lines up on crank and the copper links line up with adjuster marks, such as a new chain installed.
