need to know the max Horse Power you can run with stock 351W heads ported to the max, and polished. i am looking for around 600hp is this possible with the stock heads with alot of work, also would like to know what is a good price for getting the porting and polishing done.

I think a set of Performer RPM or AFR 185//205 would be cheaper than all the grinding on the stock heads. Anything is possible though if the engine is built right.
