If you want some more info you can ask Turbo-6 about when he divided his intake ports. He had dynoed both divided & undivided intake port heads.

IIRC, when running the divided ports, he had to turn up the boost another 10 PSI to make the same HP as an undivided port.

Also, If I have my information correct, Mr Hot Rod set a new record w/an old Sissell Lump port head. 8.9 N/A.
