Rockers look good!
There are different type of spring compressor tools, that one is cool though.
You can make one also. Long, Flat plate steel, a hole for the rocker stud & a slot or bigger hole for the retainer, Bammm! Maybe?
Hmmm, wonder what caused the ring land to let go?
Cam is shot., bearings are worn, most likely high mileage, or not changing oil enough. Yes, debris going through the oil system causing grooves.
.0035" is a bit much.
