My 422 smallblock build

Not scared at all, just don’t see the reason to use a manifold that is designed to produce power between 4000-8500when the majority of my driving will be between idle and 6500. Am I missing something here? If I planned to bracket race this car sure as **** I’d sell the dual plane and slam a Strip Dominator on it and hold it to the rug. I thought the dual plane would be perfect for my intended usage. Would a single plane make a few extra hp at max rpm? Almost definitely. Will the dual plane outperform from idle to 3500? I’m betting so.
