Not to pick on you or be confrontive, but I raced a '67 Z28 Camaro on stock spec valve springs for four years, set three national records, won one national event, two points races, class at national events eleven times, logged over 300 runs, and broke one pushrod and one rocker arm. Shifted between 7000-7200 and cleared the lights at 7500. Then I raced an A-B/Stock 396-375 with stock valve springs for four years, set five national records, won class 13 times, quarter finals at three national events, and broke one retainer and shattered two keepers, shifting between 6800-7200 and 7400 in the lights. Before all that, I raced various 283-220 equipped rides with stock valve springs for six years, set umpteen records, won many races, logged over 1200 runs. Broke one retainer, one lifter while leaving the the starting line as high as 8300 rpm, shifting at 6800-7000 and at least 7000 in the lights. Then I raced an SS/C 427 Corvette that had Billy Badass valve springs, roller lifters, Jesel, etc. etc. In 87 runs I broke multiple lifters, pushrods, valve springs and rocker arms. Left the line at 7500, shifted between 7200 and 7600, and ran 8300 in the lights. So my experience tells me the obvious.
