Match this 500hp/500lb-ft Combo?

Blueprint his this stroker SBC for sale that has a really nice torque and power curve and decent idle vacuum to boot. The 408 mopar they have falls short- appearing to be from crappy heads and lower compression. What would you guys suggest for a combo that could match this?
Would a set of TFS on a 400" engine with 10.5:1 do the trick or are w2 type heads needed?

Well ported factory iron will make that power no problem.
