Re: Best $600 heads and cam
Give a couple of reputable machine shops a call and see what they have on hand as far as heads go...most of them will have some stuff hanging around that they may be willing to part with for a decent price...
Everyone gets so caught up in the "best heads" money can buy...many stock, or slightly worked stock heads can perform very well on a true street motor, like you are describing...
If the motor will not see over 5K RPM, the old double hump heads (461 or 462's) could work very well for your build, and you can likely get a pair fairly inexpensively--they generally go for about $200-$250 on craigslist, and another $200-$300 in machine work--hot tank, valve job and setting up the springs for your cam (maybe even new springs) can get you on the road within your budget!
