Brian,
Are you working with stock or worked heads? If the heads have been worked on. Is it possible that the intake side has been milled?

Does it match the flow sheet?

Milling the intake wouldn't make that big of a difference in port length. Only thing i can think of id the min csa isn't where/what i think it is.
Thanks for the port length info

What you need to do is get ahold of your buddy Paul K and have him weld some of these thingies in there. That way you can have them any length you want.
Call it Paul K,s Variable Length Intake Runner Pontiac Victor.
Sounds catchy. Maybe he can get as patent for them.
This is Pauls actual work BTW

That added in port divider needs more roof to floor taper to it.

Port of what it does it to even out the tuned lenght disparity between the roof and the floor of the runners and the floor is short lenght wise by by the width / diameter of the Intake valve or atleast the width of the throat in the valve bowl.

Good advice.... Probably the most worthwhile post you've ever made... You should post the pictures of the finished project. That manifold made good power.... All in by 6500.
