Bruce told me directly the two part numbers I dont have the numbers here at home, but I looked them up right away and one was the existing Dart 180 cc currently legal in the traditional classes, the other IS the 230cc/49cc Dart previously mentioned, Those are the only two on the list as of my conversation with Bruce.

Regarding Mr Bogner's comment about cracking, I agree, if your heads are cracking then maybe you just went to far? I have two sets of N heads that have cracked ironically across the exhaust face from the head bolt bosses, wrote it off as just bad castings. Manned up and built another set.
