i think shadrach74 is trying to figure out, what is the best way to do that job.
if to be honest, i'm a little bit confused as well.
LN procedure say to lock the cams, and leave the IMS free.
in that case the shaft can go off-center and cause some deficolties with re installing the bearing.
on the pelican procedure, you use bolts to lock the IMS in place.
but you cannot lock the the cams at TDC.
which procedure is better? i don't know.
when the day will come (and its coming soon) i will probably go with the cam locking method instead of the IMS locking.
hoping not to end up like our buddy Hakim.
