Fresh 302, block was decked, valve train noisy

Lifter and lobes ok
There is not enough oil in the rockers arm except for one which is near the
The camshaft bearing with the oil feed hole in it. The one rocker arm is getting plenty of oil through the pushrod

So could it be possible the the cam bearing was installed partially cockeyed that reduces the oil flow significantly or the bearing spun ?

I've read some posts that stated that lifter preload on small for fords need only be off a little bit to greatly reduce oil thru the pushrods ??

Your thoughts ?
