stamped steel rocker arm delection

Chris, I never said the rocker was not a problem. It is, but there's not a lot you're going to do about it. All we can do in Stock is to work on what they let us.

The calmer you make the pushrod, the less harmonics it transfers to the rest of the valvetrain, especially the rocker. The stiffer you make the pushrod, the less it acts like a spring. The less the pushrod acts like a spring, the less of a beating the rest of the valvetrain takes. If you can stop or reduce the spring effects the pushrod drives into the rocker, you can calm the rocker as well.
