CAM timing belt marks

1.5 SOHC. There are two marks on the outer sprocket one at twelve o'clock and another at three o'clock (my sprocket has five contact points) and a knock/dowel pin and a hole just above the knock pin. I looked and read quite a few diagrams for this engine's timing marks. The crankshaft is easy to understand it has only one mark. The camshaft however is difficult, it has two marks. The diagrams show the knock pin and the hole above it to be perpendicular (straight up and down) to the head and a arrow for the timing mark located at the top of the half circle next to the valve cover. Also, just to the right side face of the head slightly below where the valve cover contacts the head there is another timing mark. All the diagrams I have looked at suggest lining up the knock straight up and down and the timing mark (three o'clock) to lineup to the pointer on the right side face of the head, okay, the marks do not line up! According to the diagrams I have seen. If I line up the three o'clock mark with the pointer the twelve o'clock mark and knock pin is then at one o'clock, Okay. I installed the New timing belt and checked for valve interference and I have no valve interference, but the cam position has slight tension and will require holding the cam sprocket to the right slightly. The car seems to run okay, but it feels a bit sluggish to me. I am thinking of re-timing the engine to where the cam timing mark would be twelve o'clock'clock straight up and down and the knock pin and hole would be aligned to the arrow next to the half circular portion of the valve cover. The difference between these two setting is two teeth. Also, that was the way it was before I took the belt off. PS. Some engines do have or require you hold the cam in position while installing a new belt. Which way is correct?
