IMS install

So I've searched the forums and see conflicting info on my question.

This is my situation. My car is in for service (new clutch, axles, bypass pipes and IMSB). I went to visit my mech and he is in the process fo pulling the IMSB. He has the crank and cam positions marked, but is not locking the the cams at TDC.

According to the Pelican tech article the cams do not get locked.

According to my mechanic, it is impossible to lock the cams at TDC and lock the IMS sprocket because when the the cam and crank are at TDC, the set screw holes are lined up with holes in the IMS sprocket and therefore will not make contact with the sprocket thereby locking it in place.

For those of you that have done this procedure, is the Pelican tech article accurate? Is it the best way to do the IMSB replacement?

My mechanic tore is finger up pretty good loosening the rear tensioners, one was so tight that he needed a breaker bar and when it finally let go, his wrench slipped and he ended up with 5 stitches in his right ring finger. Now one of his shop mates will be continuing the job and I am nervous about the direction this is going.

Any feed back on locking vs not locking the cams would be appreciated.!

Thanks!
