Hi Kent,
2200 pistons that we have had in Canada are flat top, I believe
Ruth usually gets them. My friend bought a set from e-bay and they were flat
top, we have not used them yet. Why don't you drop an email to Ruth and get
the real deal.
As the only ones we have seen were flat top we did not think there was any
other kind.
