Prototype W2 heads 700$

I don't know if he's still around or not if like to ask him about these heads,I couldn't find the casting number anywhere in a book or online .Ryan at shady Dell speed shop identified them for me said he's only seen a couple sets of these..these have never been cut for valves and rocker pads are undrilled as are intake bolt holes.they are just dirty from storage.would make someone a nice set when finished.they have a heat crossover in them.
