Curious, does the exhaust need to be pulled to do this, or recommended?
No need to pull the exhaust, it is difficult and you will need 3 hands to accomplish, one to hold the feeler gauge, one to hold the box end wrench and one to hold the screwdriver, it becomes a dance (turn that, tighten this, measure that and repeat). There are several threads on the subject, look for capt. crusty posts.
Oh its not that bad.
One hand holds the feeler and box end wrench on the nut, the other tightens the adjuster. Then just hold the adjuster still while you snug up the nut. If you find yourself tightening the adjustor screw a little when you tighten the jam nut, go with it and keep the adjuster 1/4 turn loose and let it tighten up a smidge as you secure the jam nut.
The hard part is figuring out where to get your hands up and in there, especially when you have hams like me. Once you figure that part out, the rest of it is pretty easy.
More then that - you want to avoid pulling the exhaust whenever you can. Breaking an exhaust stud, or having one pull out of the case, is a PITA, and easily avoidable.
I will say though - when I had headers on the car, doing valve adjustments was a SNAP compared to heat exchangers.
