Thanks for the responses fellas.

I hope the pushrod isn't flexing. The spring is 115 lbs seat and 300 lbs open and the pushrod is Trickflow 5/16 chromemoly .080 thickness. I get identical results with the adjustable pushrod as I do with the Trickflow one piece unit.
But if you still think I should change the springs I'll try it.

I'm missing how I'm going to check the rocker arm ratio. I kind of thought I was doing that with the dial indicator on the retainer. Is there an easier/better way?
