It just doesn't look very well thought-out from a flow perspective. It'* as if only diameters of runners and collectors were considered.

Didn't someone flow test the stock manifolds and find that the rear actually flowed worse then the front? Did we ever get confirmation on that?
I wouldn't be too worried about the pipe orientation, they are not meant to be headers and the price reflects that. Stock manifolds are usually set up this way.

New #'* are:
SII front cast iron:
Pre port/ceramic: 256 CFM
Post port/Ceramic: 288 CFM
SII Rear tubular:
Pre port/ceramic: 302 CFM
Post Port/Ceramic: 322 CFM
Now the interesting part is to get one of ZZP'* and have it flow tested on the same machine. HMMM.

Maybe on your mod weekend I should just try the front pem. then race Sat night. Would it be a benefit to have both sides flowing the same rate (or closer together)?

But he doesn't need a better flowing manifold.
