This why I tell people not to pay attention to the fly wheel. Stick a straw in it, raise it to the peak on the comp stroke, valves open and call it a day.

lmao yeah i just went by the cam marks and marked tdc on the cam and put everything back together, but i think i might have recieved the wrong head!, this thing has 6 bolt holes for the valve cover. With that the hammerhead exhaust wont even fit on the head because now its hitting the clutch assembly case, and i need to get different bolts for the elbow that the carb connects to. spent all day on the dam thing.
