unfortunately it is not a 12 port. it is similiar to a 235 head with 3 intake ports and 4 exhaust ports. With the 3 intake ports, each one sharing 2 cylinders, I guess the twin tbi would have pretty even dispertion as the throttle bodies are set in between each of the runners. as well if I ran the big intake I could just run three TBIs sitting right over the ports...of course at this level of performance having the multiple tbi setup is really just for looks as I assume having a pair of injectors shooting into the inlet plenum would be just as efficient as one injector in each tb.....the multiples would just look more old school.
