Patrick, you might as well quit dreaming. For one thing, you needn't worry
too much about such a head for your '79. You already have an eight-port
head on your car.
The works cars date back to time of the original 1147cc Spitfire engine,
with its "siamesed" intake ports on the street version of the
Herald-derived head (six ports total). A special eight-port head was
developed for the works cars in both cast iron and alloy. With individual
ports for each valve, bigger valves, use of two twin-choke Webers, etc.,
it made for a suitable increase in power over the stock unit. :-)
There are a few of those heads still around, but they're only of value to
the 1147-driving "Walter Mittys" among us.
