Because engines with true zero deck run more efficiently and make better power with less chance of detonation for any given compression ratio.
Also, if I'm not mistaken, the factory head gaskets were thinner than commonly available aftermarket replacements. Even if the quench distance was a little big it was not a problem in the era of commonly available 100 octane pump gas.
If you deck your block to zero and run a Fel-Pro 1016 head gasket you'll have .038" quench distance - perfect.
