My K9 is running fine, but I think the rocker boxes are getting louder. I'm not really sure how many miles are on it, because the speedo wasn't working when I purchased it. I put the old mileage into the new dakota digital speedo when I replaced it, so I guess it is around 20K miles right now. Should I be adjusting the pushrods or valves at this time? I run Mobil1 oil, so I know it does not quiet anything down, but it seems to be getting louder, especially a high-pitched ticking at higher RPMs. It has the stock S&S boxes on it.
