Big Block valvetrain issue advice needed

Marco-

when i first adjusted it, it was out ,but not enough to hear the noise I heard.

and by looking at threads on adjuster,under rocker, this is the only one where i dont see 2 threads under rocker adjuster at pushrod , from beginning????

Again, dont seem to here any change in accereration or misperformance as it is??

Other than sounding like .030 gap on lash????

Thanks,Dave
