oxygen sensor location?

Yup.  In your case I would target one collector/bank or the other, and be
done with it.  Maybe install a spare bung in the other collector/bank just
so that you can later move your sensor from side to side as a sanity check.
I'd use a heated O2 sensor if very far from the cylinders.  Remember the O2
signal grounding issues.  Depending upon your exhaust configuration, you may
need a "redundant ground" equipped heated O2 sensor.
