Your engine is not broken in yet, as has been mentioned. Did you follow any kind of cam break-in protocol? I'm not seeing it in the OP. If it were mine, I'd have the head checked (as recommended, though I don't see any indication of a gasket leak), and put it back together. The three cylinders with no ash indicate a potentially extremely lean condition, but #2 & #3 cylinders have some deposits. That's kind of strange, with a 1-barrel carburetor, since it should feed all equally. You don't have a rag stuffed in the manifold portion that feeds the last 3, do you? I've seen things like that. I'd highly recommend you find someone on the board near you to help.
