Weiand Dual Plane Intake

I called the guy and he did not had the intake in front of him, and did not knew the model by heart. He told me it was in very goos shape, no broken hole or anything.

I will go take a look at it this week, is there any dual plane model to avoid from Weiand?

Is it worth getting that dual plane and then trying to sell the single plane? I guess overall I should be better with a dual plane, even if it is not a Edelbrock Performer!

Weiand is Holley from what I saw, so no fitting to use my Holley 1850. rigth?

Thanks
