The kid and I installed headers on his NA tonight.  The  O2 sensor wire is too short to reach the bung on the header.  Can I simply splice in a little extra wire to make it reach?  Thought I would check before I cut the wire...

You can cut and splice the car harness side of the connector via the solder/shrink wrap method. Some O2 sensor wires(the wire from the sensor itself to it's connector) is a special type of wire,maybe silver? It can't be soldered as it will just run off. I know the Denso replacements are like that,not sure about original equipment sensors. I don't like to use crimp splices or terminals( unless using an Oem or Deutsch and use the correct style crimp tool)

It's usually stainless steel wire, which doesn't solder worth a darn or crimp very well, because it's too hard & slick. But of the two, it crimps better than solders.

How ever you splice it, remember the ECU is comparing micro volts at a very low amperage. Even a slight resistance in the splice can change what the ECU sees. Which will effect how the car runs.
