Look at this: http://hem.bredband.net/b207653/9-cyl.html
If it's small size you're after, it is too big at 124ccm, but if it's the looks, it is superb.
His head castings comes with rocker boxes and covers and are superb die cast aluminum. I have no connection with them other than being a satisfied customer. And, no, he does not sell finished valves. But you have finished your CNC mill, are there not enough leftovers to convert your lathe? Valves are meant for being CNC-produced with 9*2=18 pieces made after making just 1 program.
The only thing I don't like with the construction is that the pushers are hemispheres and thus only have point contact with the cams.
P.S. I can show some pic's of jigs for machining these heads if there are interest.
