496 plugs are about $12 each from what I recall. You really don't need to change them until probably 300+ hrs. I just changed mine in my 2000 502mpi's last year(320hrs) and they looked to be original from the black paint on them.

AC Delco 41-983 are stock. About 6$ apiece from Summit Racing. From Merc they are ~$18.
