Well I wasn't going to go there but I was just about to mention valve weight does (or should) have an impact on rocker arm life, especially with high RPM. Chris mentioned beehive springs and I would think that would have another positive impact due to the reduced size of the retainer and I assume, the keepers. Which did make me wonder why beehive springs were legal in the first place as historically the NHRA rule book specifically prohibited the useage of non-steel, non-stock diameter retainers. I believe that stipulation was in affect through 2005?
And speaking of harmonics, I know of a few stocker racers that attributed the breakage to the use of a two step. They seem to be in the minority from what I can tell.
FYI, I too have used Chis Padgett extensively at both Lunati and Comp Cams.
