G'day
Just as an aside to all this.
It's true that tha 6-port cylinder head wasn't introduced until the
100/6 Mille Miglia of 1957 however my car had a 6-port head as early as
1954/55. Geoff Healey was experimenting with that head design in an
effort to extract more power from the heavy and lazy new C-series
engine.
