Really does't matter as far as engine re-assembly as the crank pulley can only go on one way. Engine timing is determined by the colored links on the timing chains and the mating marks on the gears. The crank keyway should be straight up when installing the chains. The balancer chain should have an orange and a yellow painted link; the orange lines up with the appropriate mark on the crank gear and the yellow lines up with the timing mark on the balancer shaft gear. The primary timing chain should have three links with yellow paint marks on them. They'll line up with their appropriate marks on the camshaft and crankshaft gears, respectively. If those are all lined up properly, the engine is in-time.
