Set your timing on the crank, line it up with the straight line, not the "H" on the crank. Your cam gear will line up with the head one tooth to the left of the mark on the cam gear. The mark on the cam gear is actually right between two gears, the gear to the left should line up perfect putting the mark on the gear a little behind the head mark, probably about 1/16". That is the cam mark will be a little bit to the right of the head mark.
