Late SC cases were like that. Friend of mine had one. Interesting about the heads as well, but I can only assume it was the same kind of thing where they were migrating the parts steadily to the Carrera configuration.
Will be interesting to rebuild it... you will have to know which part to order... 3.0 or 3.2 version
Best regards,
Michael
