408 hyd roller, too much spring pressure?

Evidently you just don’t know what you don’t know. If we are now talking about stud mounted rockers (which is what happens all the time…guys like to change up the discussion to muddy up the facts so I’m not surprised you did it) then that’s a different discussion.
Back-pedalling much? You said it, not me. And now you want to quantify it by saying "But, but, but . . . I was only talking about shaft-mounted rockers"?

Why not just leave the blanket statements alone and stick to the facts? Anyway, this is all getting a bit silly and personal now.
