30-ish years ago, when replacement 273 rockers were readily available new, I built a 360 that had been running them already.
3 of them were galled up on the shafts pretty bad, so I got three new ones.
During the cam break in I started to hear some clatter.
Shut the motor down, found a few rockers had some lash.
It was a fairly stout hyd cam, I figured it didnt survive.
This was back before I was ever worried about soft springing anything.
I never really looked anything over, I just yanked the cam out.
Only to discover....... it was perfectly fine...... and so were the lifters.
The adjuster screws in the 3 new rockers were soft as butter, and had just worn right down.
The old 13 were all fine.
Put it back together with the adjuster screws from the three worn out rockers installed into the three new rockers...... all was good.
I’ve seen some pretty worn out lifters before....... but I have yet to get “the hole”.
That’s pretty ugly for 2.5hrs use.
