oil hole in lifters

So I am in need of some help. All mock-up is done & I am in final final assembly of the motor.
When I was checking for push rod length I noticed that the little itty bitty oil hole above the oil band was ever so slightly coming out of bore. Just a slight cavity with the right light and right angle you can see it. It is my understanding that this isn't good. Engine is 383 .060 over stroked to 496. Standard lifter bores (nothing special done to them).
Lifters I have are Bamm big block 383/400. Is this a huge deal Do I need new lifters
any help is much appreciated.
I had a simular problem with a SB. I found it while priming and rotating crank by hand. Prime it up and check for oil leaks there.
