The pinging is usually from pre-ignition detonation and causes the fuel to fire before it is time (before the desired degree before top dead center). It can actually burn a hole in the top of the piston among other things if it happens frequently and over a period of time.

On a NA engine a little pinging will not hurt much unless it is constant. If you are not racing the car then I would just retard the timing to 8-10 and run regular. The difference between 10 and 14 degrees of timing is about 6-10rwhp.
