I have divided a port on my 250 cyl head,it would just kill flow.
The intake port window was too small in doing so.

Only way to make it work good was to make the ports so wide & tall, it would not be made for the street,only for all out racing.

I also talked w/Mike Kirby about dividing the intake ports & he comfirmed my findings as well.
