Dual pattern cams...Black Magic or Legit?

One of the universal truths is that if an intake runner is wrong for the cylinder and the operating range of the engine it is being used with, you can not tune out the wrong and make that cylinder behave the way the same cylinder with a correctly designed intake runner would. You might be able to alleviate some of the poor performance, but you can not eliminate the damage a badly designed intake path does to the power output of a cylinder — w/o redesign.

If you are racing the car competitively, then I would suggest you have four alternatives;

1. Accept the impact of the short length runners,
2. To the extent allowed by the rules, change the intake runners to be more similar,
3. Choose an engine/intake without the problems,
4. Get a different race car.

If you are not racing the car competitively either;

1. Enjoy it as is,
2. Build your own intake,
3. Get a different car.

Fretting over 6 HP on an engine that will likely make well north of 550 HP is foolishness. You are fretting about an effective 1% horsepower difference (less by the time it gets to the tire) that not only can not be felt by the driver but requires instrumentation to measure on track!! Good driving skills vs poor or mediocre driving skills will make a much bigger difference.

If you have excess energy that needs dissipation, buy a set of worry beads and rub them regularly. It is less expensive and equally as effective.
