RE: Stock rockershafts flex with modern camshafts.

I was wondering how common is shaft breakage when using steel 427 rocker stands and the thick FPP or equivalent shafts using dual springs (350 lbs open pressure or so)? Seems like the point of breakage would be the bolt hole area and the clamping steel stand will move the point of stress out to the outer edge of the stand away from the bolt hole and to a strong area of the shaft. Also the lever arm of the cantilevered section of the shaft is shortened.
Just wanted to get input on your experiences.
Thanks.
