hughes rockers

Has anyone used the rocker kit from hughes engines. They look like they are well thought out acording to there web page. It comes with shaft shims as well . anyone?
Be sure to torque and loosen the adjuster nut half a dozen times when they are new to ensure that the nuts are fully seated. If you don't do this, one of the nuts could back off resulting in a dropped pushrod while racing an AMG Mercedes resulting in a long tow home from Monterrey.
