Progressive linkage vs straight linkage on a 2x2 manifold

[Bursonaw]

I am planning to upgrade my flathead and run dual Holly 94's on a slingshot manifold. My motor is pretty much stock with some high compression heads and a set of headers. Eventually I plan to upgrade the cam but for now am starting with the intake manifold. My question is when setting up the manifold, are there any thoughts on running progressive or straight linkage?
