looking for the right intake for my 426 stroker

it is the Hughes kit has bigmouth ported heads from Hughes ,1.6 roller rockers and lifters now running a ported Air Gap but it runs out of breath at 5500 rpm 530hp 560 tq at 4400 I want an intake that will peak at 6500 or a touch more so I think the Victor is to much I will never run 7000+ . what is the best intake for this combo M-1, six pac or Torker ?
Thanks
