Here is a quote from one of the administrators on the Dart forums/board

It is about why the iron eagle 180's were not redesigned with the platinum series


As I said before, the iron eagle 180cc heads had been created and tooled not all that long before the platinum upgrades were implimented, so they weren't quite as far behind as they otherwise would have been design-wise. The major factor, as it turns out, is one that I wasn't aware of previously.
Apparently, a whole slew of sanctioning bodies using the 180cc iron heads would require applications for re-sanctioning if we redesigned the heads and as a result we decided not to change them when we did the other iron heads, that way it wouldn't create a giant calamity with sanctioning issues and whatnot.

I'm glad you asked about this, it was interesting to find out how all of it went down.

Hope this helps to clear things up.
