if you had someone who knows what they're doing re-shim the rockers and get the correct preload, thats the best you can ask for. roller rockers are just naturally louder than stock ones. is there any associated performance drop with this noise, or is it only the noise thats bothering you? performance decreases are a whole other ballpark; that would mean trying to figure out whats broken..

one other thing, is it an individual knock/click, or do they all do it? trying to differentiate between valve chatter (needs a valve job) and rocker chatter shouldnt be hard. a bad valve will be much louder and more pronounced. just making sure what you're hearing is rocker chatter, not something else.
