I opened up the ports a bit. I was using CNC ported heads that had a lot more cross section. So, I did not want to have less cross section in the intake.
The challenge that I had with the cathedral Vic Jr. is that the cross section of the ports at the plenum were the same as my cylinder head's port entry cross section. So, when I was done, there was no port taper left in the intake manifold. It would have been pretty easy to add some port taper to the center cylinders, but would have been pretty tough to do on the outer cylinders due to the port size, port curve and plenum access.
