I second what cdowns said. Manuals will usually tell you with such and such cylinder at TDC you can adjust such and such valve, but the best way to avoid confusion is to turn the engine over for each cylinder so you can adjust both intake & exhaust at the same time. Of course, the old school way of adjusting it while the engine is running always works too. Back off each rocker slowly until you hear it clack, then slowly tighten it up until the clack goes away, then give it the extra 1/2 turn. Its kinda messy though if you don't have an old valve cover with a hole cut in it.
