Dang Rocker Shafts Too Soft

I am dealing with EXACTLY the same thing with PQ rockrs on a 440, a rocker jamnut/adjuster broke, baked off and the pushrod and damaged the rocker, now after waiting 2 months for the rocker, the shaft was so worn I had to literally tap the rockers off/over the ridges in the shafts.. I didn't have a camera, but previous post above pix very similar.

This motor doesn't have 20 hrs, and uses the questionable allen adjusters as well.

Thankyou @crackedback, for recommending Hughes
bushed shaft rockers, to be on order..





Will post pix later..
