After looking at the pictures again, I've changed my mind. Those are definately 3/8" pitch cam sprockets which double checks with the reported part numbers. The teeth on 8mm pitch cams are much smaller and very rounded, not pointy like those.

But I still can't figure out why the chains aren't seating. There's no way the chains are 8mm ones. Only the 3/8" pitch chains have big fat links like those. Is the chain seating ok on the crank sprocket?
