My brothers been running them hard on his 360 for years now-7,000 is not out of the ordinary when hes burning the tires!.He has had zero issues but our friend/machinist did drill a hole for oiling,he said that most of the rockers he sees have substandard oil hole locations in his opinion,he showed us an example when they are rotating on the shaft.He seems to know what hes talking about,if you like I could get some more info.They do seem to be a bullet proof piece and my machinist actually dislikes the needle bearing rollers.
