Cheap Ebay roller rockers. Too good to be true?

never liked needle bearings on shaft rockers . unless your moving lots of oil through the rockers . the needle make grooved in the shafts . i'd go bushed rockers on a shaft before needles . a needle bearing has so little contact area , the pounds per square inch load is very high , take that needle out replace it with a bronze bushing , load goes way down and no shaft wear to speak of . oh ya were does all that worn matl go , to your oil filter , after it gets collected in the pan up the tube through the oil pump , all that fine metal dust . no needles for my street ride , just bushed rockers .
