Percent of lost lift due to 58 degree lifter angle?

I think the loss plots as a curve. It's not a percentage, it's a function. The higher the lift, and/or the higher the rocker ratio the more loss there is. I usually account for .025-.030 when I'm planning things out but I don't normally expect to use lifts higher than .600, or rocker ratios beyond 1.5.

B3 Would be a better resource for the math...lol.

I think you have something there, but a basic percentage will give us a lot of information to use. IMHO the curve would be fairly close to the percentage. Plotting it out at the top of the pushrods, then again at the valve with race springs in place would be interesting. Then look at a spintron test for the real facts
