"The fuel we have today is different from that in the '60s, but is does not
mean the quality is worse."

Thats the key. It is different. You have to keep it in mind when tuning
your engine. The more hps/litre the engine has, the more problems You will
face if using the factory tunning data. Running on maybe the most common
problem, but pinking under load is also an issue. This is not down to
detonation resistence of the fuel, rather down to quicker burning and also
down to different float level (if You set the fuel level according to the
factory data, You usualy get lower than factory, thus running on lean
mixture on partial load.
