To be honest, I am not exactly sure about honda motors, but I rember with my old Celica there were timing marks on the cam gears. So when the motor is at TDC (top dead centre) (aligning your crank pully to the timing mark) The marks on the cam gears should point up. That was with my old Celica so hopefully somone else and comfirm with you car.

But the first thing that comes to mind when you said that you timing belt snaped is are you sure you did not bend any valves?
