on # 1 it is simple, rotate engine until the timing marks say 0, now if you pay attention to the way the cam rotates, and you know the firing order, when you are done with # 1 just rotate the motor until the next cylinder in order has the cam in the same position for that cylinder.
and so on...

EDIT*
oh, I suppose it is important to make sure #1 is both lobes up, so it's on the compression stroke, and you have a simpler time removing the springs.
