Look above in post #28 in this thread, Don's (IToldYouSo) quote tells us he uses NGK plugs over all others, and that's what I use in my SBF, too, recommended by my engine builder. I believe they're head & shoulders above the old standard AC and Champion brands, which I believe are assembled in China now.
