Rebuilt magnum 360 Noise

What rockers did you use and did you clearance the top of the springs and retainers to the underside of rockers. Ran into this on several rockers even high dollar T&D. 340's were notorious for this when using 318 rockers on 340 heads. You will hear them at lower RPMs and then the noise will go away. With solid lifters it is not noticable.

Rockers are stock. Everything in the valvetrain is stock for a magnum 360 minus the cam and valve springs. I will post another video here in a minute that can help hear the sound.
