For the hell of it I installed a set of comp cams 19001 roller rockers. This in a stock z/28 302. The 30/30 stock cam requires a 0.30 lash setting. However I read somewhere that roller rockers lash should not exceed 0.12? A little help here. Are you guys running factory cam lash settings? After I installed the rollers I set the lash to 0.26 cold. Haven't checked the setting after ran hot.
