88 mighty max 2.0 carb engine rebuild

Do I line the camshaft sprocket up with the top line in the picture (the line where the valve cover meets the head) or the bottom (the line inside the head). Confused because the haynes manual is not very specific and shows the camshaft sprocket level when timed correctly. But if you line it up with the bottom line in the picture, the camshaft sprocket is tilted counterclockwise. I'm having some issues getting the timing to 8 degrees.
