Id love to build a small block with a set of those heads...oops did I say that out loud..

Good info here
There seems to be some many versions on the W2 series head though, and not much info about them, I mean they all seem to carry similar parts numbers. I have seen some good deals at the swap meet, but don't know crap about the head.
