The chart that you're refering to has nothing to do with valve adjustment. It's a "cam timing" chart. It's lightyears beyond what you're doing...please, ignore it and just adjust the valves. You can spin the engine all you like in a clockwise direction. Just follow the firing order of the cylinders and you don't have to spin it more that a couple of revolutions. No need to read the marks on the balancer, just make the cam lobes face away from the rockers.
