The only time a value will be permanently saved with an item is if it doesn't match up with the value from the code. This means that if something on an item changes and nobody has modified that value (via admin editing or the sort), that value will continue to stay matched up with the code.

Once it's been modified, however, there's not much to be done; since I can't just prevent those values from saving outright (that'd get rid of the ability to have customs/uniques)
