Hi volume oil pump vs standard volume pump

Ok thanks. I am taking it from reading this is what i already surmized. That on a rebuilt stock or mildly hopped up engine with stock clearances that a standard volume oil pump will be just fine, and a high volume pump will offer no real additional benefit, and may in fact actually hurt performance. Rounding up parts for a mild 318 to build up with my kid as he gets older. Figured a stock volume pump would be just fine for what we will be doing, but wanted to verify what i knew.
