I never used any loctite. I just hand tighten the studs, then put the rockers shafts and holddowns on with the nuts and torqued to final.

You might need larger diameter pushrods.

If the rocker studs are moving around then something is making them move. Most likely suspect is that your pushrods are not stiff enough. Call Manton and tell him what springs you are using, what RPM you're running and ask him what you need.

If that is a dead end then maybe your rocker shafts aren't stiff enough for the load. Step up to a thicker wall rocker shaft and things might stay together better.

The harland sharp shafts are definitely NOT the problem, they are very thick and rigid.
from here I cant go back and see what you are using for hold downs (will assume the harland sharp hold downs too) no problem with those either. and bolts or studs?
