360 stainless steel roller rockers on ebay, too good to be true?!?!?

DO NOT BUY PROCOMP ROCKERS !!!!!! buy if you must, but a buddy of mine bought a set of rollers and one broke in half with less than 100 miles on them. they sent him another set, 2 broke, diff cylinders. 1 year later, fighting a refund but was only given store credit.... now running a set of comp cams rollers without any problem. If your running STOCK cam, you might be ok. Any decent amount of lift i would stay clear away ! ... good luck to ya ..
