W2 parts! What are they worth?

So I've got a pair of ported W2 heads and an Eddy W2 Victor intake. Intake manifold is ported to match. Heads were professionally ported at some point. The heads have valves, springs, retainers and keepers.

I'm looking to sell, as I need to get some ported LA heads for my 360 I'm building.

So what do I have and what's it all worth?!
