Slow 96R,
The Ross Machine Racing parts are very good parts and I have used them before. The oval extruded tubing and velocity stacks work well on stock to mildly modified motors but they will start to restrict air flow on higher flowing heads.
I know snickers has in the past made a few intake manifolds with these parts, and then changed suppliers but I would have to check with him on that to be sure.
The Flow number of the intake manifold itself is not completely useful as it can be somewhat deceiving. The intake manifold alters the flow characteristics of the cylinder head because it directs the flow of the air into and through the port.
The manifold you have pictured in your Photobucket account is a nicely fabricated piece. I do have one piece of advice though. It appears that the intake runners are perpendicular to the intake manifold flange. The runners should be at the same included angle as the intake ports are in the head to keep the direction of the intake flow continuous without having to suddenly change directions. If you flowed the intake manifold on the cylinder head where the air had to suddenly change direction turning into the intake port, no matter how slightly, you will have a slight loss in velocity, pressure, and lose flow as well.
Snickers has a flow bench if you need it flowed vs another intake manifold.
