You can do it. Patience is sometimes needed when you have a keeper nut that wants to stick and change the valve lash clearance every time you tighten it. One thing thats essential for a valve virgin is a simple diagram of the valves from back to front, labeled intake and exhaust. And numbered 1-5. This way you can check off which valves you've already adjusted. It gets just a little confusing the first time because as you turn the engine 90 or 180 degrees, I forget which, the order of adjustment isn't linear, it jumps around. The first time I did mine, I ordered a set of wrenches that came with a new valve cover gasket and a printed diagram. No sweat. Also, in case no one has mentioned it, it's much easier to turn the engine via the power steering pulley than the crank bolt.
