I would need to send these out for porting (if it goes that way). Can anyone reccomend someone who would know what to do to these heads? For a fair price? $400-$500 would be fine...
Personally I'd follow curtis73 recommendations, spend your money on a set of heads with a better approach to the valve. The extra cubic inches of the 383 will love the increased flow potential.

If you’re really determined to stick with these heads go for it. Plenty people still run them. Your desired 500 HP will be more difficult to find but still with in reach. If you decide to spend the bucks on porting make sure you go with some one that knows what they are doing, plenty can go wrong when dealing with the wrong person.
