Default Lifter bore problem

I need to find out how much lifter bore clearance is acceptable. I had some issues with low oil pressure in a race engine of mine and one of the lifters got a bit stuck in the lifter hole. I had to use a pry bar to remove it and it looked scorched.
I dont want to throw the block away but may have to.
any easy fix for these?

block is sbc 509 casting.
lifters are solid roller, crower I think.

The lifter bores in that block can be bushed back to standard bore or they can be machined to .875 and no bushings or even .904.
