Eather of the 2 stock sensor locations will be fine.  I wouldnt pull the
engine... but my engine has alot hung on it so it would take longer anyway.
the sensor needs to be THERMALLY attached to the head... thats not as easy
to do as you may think.  The head needs to get the sensor up to the same
temperature at a fast rate, otherwise the FI wont track properly.
