I went with 1.65 rockers though to net a higher lift than before to take advantage of these heads, which should support 550hp.

I think you should be able to get pretty close or achieve that. I saved this article HPP did a long time ago and got 462HP out of an iron head 383 pontiac.

I would imagine with the better flow numbers out of the KRE or Edelbrock heads 500hp shouldnt be too difficult.
