Well, a big cc flathead with low octane fuel will knock.... bad chamber design.
Happend to me when we traveld to Wales for the Pendine Sands racing.
Best cure is 102 octance German fuel. Second is octane booster.
I run 24 degrees at 2000 rpm. Nothing radical.and not needed.
But i also think that a knock sensor is not needed.
