So, are the cams only supported right in the middle with the ends sticking out into space? Maybe I'm missing something, but that pic doesn't look right. Also, I wonder what that big boss on the outside-center of the head with the hole in it is for?
Looks pretty much how the cams are supported in the current camhead motors. The boss on the the outside edge of the head - possibly to mount the shaft for the cam drive gear? - yes I think I saw gear driven cams mentioned somewhere.
