Hypothetical 318 Builds

So.. i'm curious.. is the oiling as bad in a small block like some people make it seem? I had a lot of friends spin bearings in small blocks when i was a kid.. but prolly stupid driving..

I see the mods like the crossover in the lifter valley and tubing the oil passages and **** and wonder if it's needed...
Think that mod is more for high rpm endurance engine maybe super high rpm drag.
My cousin stock car would hit 7000 rpm on the track with stock oil system no damage over several seasons, lots on here rev well into mid/high 6000's without the mod don't hear any complaints.
