That statement was obviously formulated from reading enthusiast magazines. The other side of that is the dependency that guys like Bill actually had on OEM engineers and people in the same field as Bill who had more experience that Bill would call on occasionally.
Anyhow, don't drill gaskets. Just get the right ones to begin with.
Guys at home can't measure what actually needs to be measured, so they dink around with gasket holes, extra lines & hoses, etc. and trick themselves into believing it's better because the water temp gauge, usually probed from the water outlet area, shows a lower number. It does that because the cool water is "short circuited" from the trick mods & winds up flowing out through the area where the temp sensor/probe is, instead of flowing through the as-designed system & grabbing more heat from the cylinder heads on the way through.
Places with budgets, real test equipment, and talented, knowledgeable people are the ones who should goof with gasket holes & auxiliary plumbing. Pretty much nobody else should.
