Really appreciate all the replys on this thread guys. I did learn from it. When i originally posted it, I thought that the valve did get closer to the cylinder wall as it opened, But thought it was the lifter side. So there is something learned here anyway and yes it looks like there is a loss in hp with reduced valve lift in my circumstance. The simulators show about 4hp loss going from 1.6 ratio to 1.5. Something Harland Sharp told me the other day, When checking rocker ratio with checking springs, the ratio may be as close to 1 full ratio higher, but when you install your heavy springs, it brings it back to or close to the advertised ratio.
