What's a set of 455 "C" heads worth complete?

Like the title says, what are the C heads from a 455 worth? They are complete with pushrods and head bolts, of course the valve train. I know where I can get 2 sets.
Thanks.

I saw a guy on Craigslist that had two sets. He wanted $200/pair. But if you want a set I would snatch them up now. That price will do nothing but go up.
