Can you get a before and after of the throttle bodies, upper and lower bolted together?

Yep that's next, sent some to him just now.

I know it would be a lot of extra work, but it might be important to know the flow of each port through the whole assembly including throttle bodies. The idea is to make each port in the assembly flow the same. Luckily this is not wet flow so that should allow more freedom to shape ports to achieve equal flow in all the ports.

That can be arranged and should be done to make sure the performance in all cylinders is the same. The problem is to do that on each build would sky rocket the cost of porting as the porter will have to go back and forth multiple times.

Agreed, flow bench matching in production would be cost prohibitive. Based on some experience I have had in the far past with v8 manifold porting there are probably some areas in every upper and lower manifold that need to be touched and some areas that should be left alone. Find those areas and verify with flow testing on one prototype pair of manifolds, then duplicate the pattern on production manifolds. The matching won't be perfect but chances are it will be better than stock.
