In Bubba;s post he posted about making sure the 3 oil return holes, "oil drain back holes" are clear and full sized, they are located between the lifters, to drain oil to the pan. But you skipped over it . Also if the rod oil spurt hole is facing the cam it will throw more oil up to the lifter valley "lifter galley" it goes the other way,but the oil spurt hole will not cause your problem alone.
Blow by looked higher than what it should be but I could be wrong.
It is not the cam bearings. The front cam bearing has a small groove in it to lube the cam retainer if it was wrong it would be a minor amount of oil ,still below lifters . 2 and 3 have one hole ,if they were off no oil would get to the journal and burn up , the last bearing has a slot that oils up to the rocker shaft and you know it is working. The bearing are each a different size and the cam wont fit so they have to be in the right order. But I guess any thing is possible.
