Don't pay attention to the amount of adjustment, just set them about half of the lifter travel. How to do that is, while the engine is running, loosen the adjusting nut till you hear ticking, then tighten the nut slowly till you hear a miss. It make take a few times to find the point of a miss, but this gives you a idea on how much travel is in the lifter. If you use about half that amount, you will be good to go.
It sounds like you are on the road again, so recheck the rockers in a week or so. If it does it again, then you will know it wasn't your doings.
