Since I actually own most of the paper manuals for the things being discussed... in this case the 615, 616,617 NA manual.... I am going to go look at it... with regards to the vacuum pump removal.
My initial impression is that there is no way I would take the valve train apart...what advantage is that supposed to provide ?
What really counts is KEEPING TENSION ON THE CHAIN DURING THE CHANGE OVER.
There is also a special tool which clamps above the cam sprocket to KEEP THE CHAIN in CONTACT with it during this procedure... the combination of those two things should make for good results...
I highly recommend reading the 616 manual due to the warnings which are presented no where else... even the Haynes manual does not present all the needed warnings which are in the FSM.
It is important in our engines with regards to chains to replace all the things IN CONTACT with the chains... rails, and that sort of things
