Small block Hemi heads

This cold weather must be freezing up my mental capacity. I got to thinking about some small block hemi heads which were being developed a few years back by a company called Rod and Custom Machine. Only saw pictures and a Google search turns up plenty of mention, yet their website seems to be in forbidden territory and all the references are at least 5 years old.

Also found some info about a company called Arao Engineering who claims to have a 32V hemi head for Ford and Chebbie small blocks. Seems to be some very negative experience in dealing with this company, but their website appears to be current.

Maybe the whole point of this is old news and we do have the new hemi to keep us satisfied, but the idea of making an aftermarket aluminum head of hemi design for small blocks does seem to be feasable. Has anybody actually seen one of these hemi conversions? Does anyone know what happened to the companies mentioned?
