Ross,
For what it's worth I can't find either of those numbers in the
parts books I've got, although they don't list the rare 8 port mk1 head,
and might not include all the US variations.
However, I had a look at the pictures of the 8 port head in the Robson
'Spitfire and GT6' book, (page 54) and that only shows only 4 studs on
the carb side of the head, instead of 6 as on a normal 1147 engine.
Presumably there are still 5 on the spark plug side making it a 9 stud
head.

I think you might be getting mixed up here, the mk1&2 head has 11, the
mk3 (1300) has 10.
Sorry to be the bringer of bad news but if it has 10 stud holes (5 each
side) then it probably is a 1300 or maybe even a 1500 head.
