I have watched a bunch of videos of modern NASCAR engines being built and it seems they use a combination of that and shimming the rockers up and down a few thou... that surprises me a little as it makes it seem as if they are not super concerned about a tiny bit of rocker arm geometry... or maybe I am just missing something?
