i've built a bunch of Mopar V8 with solid roller cams and lifters, when I used the cheaper rocker arms and pushrods like the old Smith Bros pushrod without the heat treated end they did wear and require more frequent lash adjustments
One i switch to Harland Sharp and T&D rocker arms and Manton series 3 or 5 pushrods the valve lash adjustments almost went away, once a year or less after being broken in
Good parts are worth buying and using
