he was suppose to post pics of his broken rockers. guess that isn't going to happen. i bet the retainer is hitting the rocker. when i rebuilt my engine 2yrs ago, previous builder didn't have the stand shimmed properly & the retainer was just scrape the blue off the rocker. these are the blue t&d's, 1.65- 1.60, sb, w9's. i have a perfect scrub pattern, no problems. seeya.
