Super noisy valvetrain in my Magnum 5.9

Hey All"

I'm running a Magnum 5.9 engine in my Dart. I revved a little higher than I intended (about 7200) and picked up a tapping in the driver's side (probably #1 or #3). So, I pulled the lifters and replaced them with Mopar deals from Mancini. Also bought new Magnum pushrods at the same time. I'm running the stock rockers and the springs are whatever Hughes puts on their Iron Ram heads.

Now, the goddam thing is noisy everywhere. Sounds like a tractor or something.

I installed them the same way I did originally. Basically, turn the motor until the cylinder I was working on was "Off-lift", torqued the rockers to 20 ft.-lbs and moved to the next one.

This is the method outlined in the Mopar Magnum engine book. Can't figure out what I'm doing wrong.

Any help is appreciated.
