Spring/Keeper interference with Rocker

Cut by the springs, that spun when they bounced, and it happened early on at break in. At some point those rockers we might have even been run backwards r on l and l on r etc. ... but either way they arent cut uniformly, they are cut per where they interfered and only where they interfered.

What is the installed height?
The retainer can look higher as long as the spring is shimmied to spec. There are only 90 or 100 pounds. Setup tall they will let that heavy 3/8 stem valve dance the dance of life. Look for dug in spring pads.
