You should also add the sticky bit to their directory (chmod +t) to prevent them from replacing these files.
I feel the need to learn something new today. How could the user replace the root owned files in a directory that they own?
By renaming or unlinking them. Linux treats this as an operation on the directory, not the file, so it's controlled by the directory's permissions.
