Had the "unavailable" Ebrock Victor in my hands this weekend in Vegas. Thick deck, indicated that they left material in critical areas for port work. Extra row of bolt holes for the R3 crowd. Raised valve cover rail (anyone who's owned a set of W5's will appreciate that). W5 exhaust port flange (maybe I'll do a build someday around the headers hanging on my wall). ""IF"" these heads would have come out in a timely manner it's what I'd be running. We had two 340 blocks, the headers, and could have made spacers to run our intakes. I loved the performance we got from our W5 mill. It would have been nice to have that same deal with a reliable head of quality casting.
