Jarrid,
Very good advice. My machinist has a special fixture on his Sioux
machine to correctly reprofile the rocker arm tips, and the thought of doing
them on a belt sander makes me shudder.
Also, there is usually a wear pattern on the sides of the rocker arms
from the direct contact of the coil springs between them. Sometimes it is a
significant "step" and the springs follow the motion of the rocker arms,
winding up and relaxing with each opening and closing. I refinish the sides
of the rocker arms myself and install hardened shims to isolate the springs
from the rocker arms.
