Default How much more lift will Pro Magnums give?
If my cam specs say .588 lift, what would that increase to by adding a set of Comp Cams Pro Magnum rocker arms? They are a 1.75 ratio vs the 1.7 stock

max lift / stock rocker ratio = actual lobe lift
actual lobe lift * new ratio = new lift

I think stock are actually 1.72, but I could be wrong on that.
