I have run HS for over 20 years. I ran HS on the wides car for over 25,000 miles after taking them off my 2 yr old roller combo. Still on her car. My current CV-1 uses HS as did the same engine with E-heads before it. Use them with 400 plus open (beehive springs)and 6600/6800 rpms constantly. Never had ONE issue.
My deal. If it taint broke don't fix it.
BTW: they started the roller rocker industry.
