Info on the weiand 8007

Does anyone have any experience on the weiand 8007?

From a bit of research I've found (through an older hotrod.com article) that, "This is Weiand's competitor to the Edelbrock Performer and also has 318-sized small port exits. Like the Edelbrock Performer, it will improve with a 360-sized deep port match".
So could I assume that the "small port exits", are just that, and a "deep port match". is just gasket matching the small ports to 360 heads?
Reading the whole article it seems as though the 8007 has large runners that tapper down to smaller 318 size exits?
In the article it simply reverts you back to an earlier description of the edelbrock performer.
Here is a link to the article.
Interesting read anyway.

Mopar Small-Block Intake Manifold Flow Test

Anyone ever do a flow test on a weiand 8007?
Anyone have any positive results from this intake, besides weight savings?
Also what is this thing people are doing with dual planes where they cut a section of the top divider? Is it to help with all around flow? bottom end power? top end power?
