Using 33000uF caps in PSU?

To keep myself bussy, I've ordered a stereo LM3886 kit including one PSU board from From my last project I have 2 33000uF/40V caps left. Does anyone have any suggestions as to how I might implement them in the standard PSU? Are there any benefits of doing so, and do I need to change a hole bunch of other components (not that there are so many to begin with...)
