i can believe you when you say that Hulk and Thor are meant to be equals; they certainly started out that way, with Stan considering Thor god-status as stronger at the start, but Hulk just able to match him through his dinamic factor. But it's also true that a varied number of authors diverged from that significantly at times. Hulk's limitless growth has not been mirrored by the others, since neither Thor/Surfer nor any other has demonstrated "limitless" amping, but a finite power reserve...
