The most obvious things are as follows:
The smaller port heads > Have round inlet port runners and the divider on the inlet ports is nearly flush to the mating flange of the head.
The larger port heads > Have D shaped inlet port runners and the inlet port divider sits approx 20mm lower than the mating flange of the head.
If you were to ever put both side by side the difference is apparent. Or alternatively PM me a pic of the inlet ports and i will tell you.
Hope that helps

These are bigport ones.
On the uk small port ones the vane/sepertor runs right to the top.
