Super bummed. New motor. Bad bearings?

Muscle Motors had an article on cam tunnel core shift. Maybe check it out. Can You even install a mopar cam bearing in the wrong location.. or not have it not fall out?
I believe the cam bearing bore's are stepped, smallest one is to the rear of the block, largest to the front.
I dont know if you can install them out of order.
I guess with a big enough hammer anything is possible.
