You don't need to move the phase sensor as the distributer blank cap you can get fits over the phase sensor. Unless of coarse you want to remove the distributor all together then that is when you need to machining as you need one of the cams extending with a trigger and the cam cover machineing to accept a sensor to pick up on the trigger, which in my opion is to much hassle.
Just fit the kit open your plug gaps back up and enjoy.
