Tim, I have used both the Crower and T&D rockers. I personally have never had a problem with the Crower's but have repaired problems in cases where customers have installed them. Usually the problems arise with incorrect installation. I have cars with over 20k miles.(knock on wood!) The Crower's are economical but the T&D's are almost fool proof. Pull the valve covers and visually check them once in a while. If you beat the thing hard, at least have pushrod guide plates, or better yet, T&D's.dj
