Greg, I agree with this up to a point. 90% of the people we talk to are not talking about stocker level stuff. Their experience is with high lift, high spring rate stuff. Talk to Sacha at Trend. They have some cutting edge stuff right now and use a Spintron as well as some other tools for R&D. My 1.72 intake valve will take a different spring rate and pushrod diameter than a 2.02 cylinder head. It just doesnt automatically cross over....
