OEM Rocker Arm Side Play

Got any OE rockers to try and see if they’re just as bad?

HS sells shims in various thicknesses you could use to tighten that up.
Yes, they are the Same dimensions. I guess it’s just good old oem tolerances. I’ll look into those shims. Obviously some side play is needed just need to settle on how much. Not building a race engine just a fun street performer for my son, could just bolt and roll but..... again, just very sloppy!
