I have ran HV oil pumps in all my rebuilds with stock pans, never one time did this happen. Even with hobby stock race car engines where the rules state you have to run a stock pan.
Not a myth, as I said it happened to me. There were no drainback issues, block was very clean, oil return holes chamfered, Glyptal on the lifter valley and timing chain area. Just because you never had a problem doesn't mean no one else could have a problem with their setup.
