Yes, the angle of the bowl can depend on the car. I have H6s on both my
TR3s and on my Healey, and the bowls are at different angles. As I
recall, that's about the only difference. Fuel line attachment can also
vary.
A friend of mine put SUs on TR6, years ago, and the performance increase
was noticable.
Sorry to say that I am no help on your other questions.
