That "picture" is just a rendering. If they ever reach the market, they'll probably look different. Hopefully they decide to put all of the head bolt holes on the finished product. I imagine that since they are mostly hiden from this angle under the exhaust ports, the CAD guy just left them out of his drawing.
With a 2.15" intake valve, they will also have to move the valve over. That will raise the price of available rockers.
