Not Ranked
I've personally gone that far (10,000) and more with plain vanilla Comp lifters - but the next guy you see in the parking lot seems to have trouble getting half that. Never have "figured it out" but it does happen. FWIW - I am a fan of tight lash, really good quality springs that are firm enough, and high idle speeds (1000-1200 min).
