We don't use the IP lock pin for setting the timing. The IP cogged pulley is keyed to the shaft and has a small groove in its outer edge that coincides with the fine straight mark on the IP body which will approximately indicate IP TDC position, close enough to correlate with crankshaft and camshaft TDC, close enough to get it dialed in with the dial indicator.

Sorry for the non-concise formatting of the important sticky IP Timing but I suggest studying it and following its procedures.

The IP can be locked down to its mounting bracket in a position a little further away from the engine (to ease R/R of #6 injector GP) without ill effect, as long as the injection high pressure lines are not stressed.

The rear camshaft pulley does not use a key as it needs to be able to rotate freely (until you tighten down the fixing bolt) on the end of the camshaft to set the timing.

Creative workaround on the crank pulley holding tool. Will it work on the other side of the fan pulley snout when tightening the crank pulley bolt? I presume it is not resting on the fan hub, to protect its bearings. How do you plan to set the high torque on the bolt?

The Dogleg 17mm offset wrench is a great help dealing with the rear camshaft bolt.
The Cam pulley holder is a must, for approaching and attaining the desired timing setting.
The Injector line wrench sure makes R/R the injector lines almost enjoyable!
