OEM magnum lifters setup

Brought back from the dead and I think you just did me a favor. My lifters also bleed down and the valvetrain is quite noisy in my magnum. If I'm reading this thread correctly, going to a slightly longer pushrod could solve both these issues? If so I'm sorry I missed this thread last year. It would be pretty inexpensive to give it a shot, is ~.033" longer still the way to go? Like this?
