A better solution is to save your OEM pulley, label it, toss it in your spares bin and don't shave off too much of the timing boss. This is what we did and the IMS retrofit was reasonably uneventful. It took an extra 30min or so to re-install the original pulley and align to TDC. Lock it in with the factory pin and we were good to go. Most shade-tree tuners don't think this far ahead and get in trouble when the motor needs internal work.
