David, I can't answer your specific question but I do have some things for you to consider. When someone "recommends the Victor junior for best performance," what kind of performance are you expecting? Do you plan to do track day events with your car? Is it just for cruising on public streets? Are you a drag racing enthusiast? . . . This matters because a Victor Jr manifold is optimized for operation above 3500 RPM. That's great for track use where peak horsepower matters, but not very good for street use where torque and responsiveness are what matters to most drivers.

It's been my experience that many engine builders want to sell cars with big peak horsepower numbers because it sounds impressive and helps bring in more customers. But those engines are not as much fun to live with in a street car. So, when deciding what components will best fit under the hood of your car, don't let your desire to own a big HP number make the task more difficult than it has to be. Let the engine builder know how you want to use the car and you may find that a low rise, dual plane intake manifold is the best overall solution. IMHO.
