Vavle Adjustment- How Hard?

[pwagon]

I've used the lovely search button and read the step by steps on doing a valve adjust on this forum and also the pictorial at dieselgiant, but I don't want to get in over my head. I change filters/belts/fluids, but I've never popped off the valve cover. People seem to indicate this is fairly easy to do, but I'm wondering exactly how easy.

so, on a scale of 1-7
(1= programming stereo and 7= rebuilding the engine) where does this fall?
