Why don't you indicate TDC by observing movement of the number one piston. Either pull the head and dial it in or carefully use a tool like a thin screwdriver in the sparkplug hole (with the cams out as suggested) to watch when the piston stops coming up and then continuing rotation until it starts going down. In between those two points is TDC. That should get you to a point where you can make sense of the marks on the crankshaft pulley.
