What cam are you using? If it is stock then ticking shouldnt be a problem, but if you have a cam dynamics energizer series (now crane energizer, same thing though), particularly the 266 grind, then you may be fighting this all the time until you put some poly locks on it...for some reason the 266 seems to beat the heck out of the valvetrain causing the rocker nuts to back off. Other than that, heres a couple other things you need to check. Did you use new rocker nuts? Rocker nuts are made to pinch the rocker stud to help keep the valves adjusted...however, if they have been taken on and off a few times they lose their grip and will back off in a short amount of time...you may just need new ones (use polylocks instead though...they arent as hard on the threads and you can lock them down which keeps them in adjustment longer). Those stock type rocker nuts have a tendacy to chew up the threads of the studs...unfortunately, you would have to pull the heads and have screw in studs added to fix a damaged stud. One last thing...if the valves start clattering again yank the pushrods and roll them on something flat...a piece of plate glass works best...and make sure one or more isnt bent. You said you had one of the valves adjusted too tight...this can cause a pushrod to bend fairly easily. Be sure and check them all.
