Has anybody have a set of GM replacement rockers that are L & R stamped ? Can you please take a look at them and tell me which way the push rod offset is for "L" and for "R" rocker . If looking straight down on the top of the rocker arm looking at the stamping . which side is the dimble on the rocker arm ? Left or right ? I trying to track down a rapid wear problem with my retainers and want to make sure these rockers were stamped right . Thanks.
