I have a new CHP 347 with all roller valvtrain that I swapped in addition to a number of other upgrades. Projects combined took some time for me to work all the gremlins out (yeah, I admit I took my sweet a$$ time too...). Anyway, I now have the engine running and tuned really good and have been putting a few miles on it, probably clocked 150 miles now. Is it normal to check and adjust the rockers as part of the break in process for a new engine like mine? If the valves need adjustment, what would the symptoms be other than being noisy? I'm running AFR 185 heads if that matters.
