Consider the old saying, "If it ain't broke...don't fix it".
Kurt points out how easy it is to change, but there may indeed have been a method to the PO's madness. Unless you are experiencing a problem, my suggestion is to let sleeping dogs lie.
The first US JHs did have 115/115 timing that was later changed to 110/110, then to 100/110 for emissions. Further revisions in cam durations over the years gave us 102.5^ and 104^ lobe centers in the Esprit/Excell engines.
None are really 'better' because by now every engine is unique and the only way to tell is to use a dynomometer.
