Too much lifters preload
I'm with Rob here, but, I think you are going to do what ever you want.
But think.......if you lift the rocker shaft up from the head you also change the distance to the valve tip. So......if you raise the shaft .035" you will change the preload at the lifter approximately .058".
.035" at the lifter and .023 at the valve side = .058"
.035/1.5 = .023333333 (because of the 1.5 rocker arm ratio).
I'm gong nuts. I'm wasting too much time on these stupid forums.
