Now what do I do? 3.0L rebuild
 

So I'm disassembling the heads while my wife and father-in-law are in the garage with me painting some fence sections.

I'm removing the rockers and bagging them like Wayne's book says. I must have been distracked and the next day when I did the next head I found I had bagged some of the rocker assemblies and marked them all from the exhaust side!!!

Now where does that leave me for re-assembly? I planned on reconditioning the rockers and installing a John Dougherty cam that will use stock components.

If you're reconditioning rockers & getting new cams, you don't need to mark the rockers.

Yeah I`m like you, I hate working with people around me.

What about the bushing the rocker rides on as well as the position on the case?

Is that something that may have a unique wear pattern if you are replacing components rather than installing new?

You are never going to get the rocker shaft in the same position no matter what you do. What I did was turn the shaft over so the wear was on the top. Even though the wear was imperceptible, this gave the rocker arm a new surface to start from.
Porsche did not specify a side clearance (that I could find) so the position on the case is not a concern from the design point of view.
With a new cam, the cam riding surface of the rocker arm should be ground flat and smooth and the bushing should be replaced. This makes all the rockers identical. If you wanted to replace the rocker shaft, you could ensure virgin mating surfaces. But I think the rocker shafts are hard enough and the tolerances are close enough so that it should not matter where they go in the cam towers.

+1 to Mark's comments. Also, reconditioning rockers usually includes re-bushing.

A slick performance mod, and a nice way to restore a couple microns of tolerance to the rocker shafts, is to have them coated with dry-film lubricant.
