Roller rockers [at least the ones I have seen] also have a roller at
the valve tip, sincerely reducing side loads on the valve stem,
extending guide and stem life, as well as the tip and rocker. Not to
mention the life improvement from running antifriction bearings on the
rocker shaft. Make sure there is sufficient lube getting up there,
though.
