Should one be comfortable with the holding power of the 4 bolts to hold the cam long term?

I thought the theory proposed is that you want to retard the cam by one tooth.
Undo the gear, rotate the cam a little clockwise and refit the gear one tooth clockwise from where it was previously.
You don't need to worry about the lifters and such.
