I've known people who run .020 quench. I've never read one single time about .035 being minimum, but I have read that .035 is OPTIMUM in just about every article.
That said, Plenty of engines run without quench and make plenty of power.
So true. Quench is over rated unless you are talking about early SBC junk. Specifically, the spark plug location on the SBM is about the best it can be, outside of the Hemi. That's more important than quench. By a long stretch.
