either of the gm heads will work very well. a good 496 can be had very easily and cost effective with the Scat crank and rods with Mahle or Wiseco pistons. a rotator capable of making and handling up to 1000 hp is around 2000.00 with 4340 int/bal crank and good rods w/ 2618 material forgings. as far as keeping the cost down, i would just keep it basic. an engine like this with alky and either heads will make from 700-775 hp. so just use common sense and if you don't have money for heads, use what you have let alone go buy a billet crank and rods! keep it simple and it will do the job.
