Response to reducing bore

i have read Dyno Don like large bores on his cleveland to unshourd the valves and make the heas flow even better. i think he used 4.08 bores , thats why they furnas brazed the block back then to get the large bored. Granted i wasnt there. just what i read. I would like to know how much more power he gained doing it
