How much do you think a set would cost if its already had the work done to them?

Is there a perfect set of parts ( 500hplx ) said "Matched to the right combo and a power adder, they will make enough power to break a stock block!"
You speak of cam, intake manifolds, and headers when you say THE RIGHT COMBO??

Does anyone know how much it costs to machine heads?
What parts would I be looking at to buy?

Maybe I need to try to find another set already done the work to em.
