you know, perhaps the best way to approach this is by using just a smidgen of logic. there's really only two basic things that will cause what happened to your cam bearings. it's either lack of oil, or it's lack of clearance. of course lack of clearance can be for a large variety of reasons, but it's still a lack therof.
not to be too critical, but based on your pictures and the fact that you only have 25 minutes of run time on the engine. i think i'd go back and check the clearance on those mains as well. you really shouldn't have shiny edges and shiny wear spots like what the pictures show. basically they should look like brand new still if the clearances are correct.
so anyway, are you sure all the holes in the cam bearings were lined up with the oiling holes? one can't really see much of the cam bearings from the pictures you posted. best of luck with it. i'm sure you'll get it figured out.
