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.

You nailed the essence of my question. The pelican article calls for the sprocket to be locked with set screws (AKA grub screws) using the threaded holes for for the IMS cover (as shown in the pick meir posted). The problem is the sprocket has holes in it as seen below.



There is no way to lock the IMS sprocket at TDS as the holes in the sprocket line up with the set screws in that position. TO lock the IMS sprocket, the set screws must contact the sprocket and not one of the sprocket holes. To put the IMS in a position where it can be locked means putting it somewhere other than TDC...

SO, should I lock the cams and ignore locking the IMS sprocket with the set screws? I cannot do both. This is the question I'm asking...
