These valve adjustment screws are only to be used as a replacement part for the rocker arms 1:25 and 1:40 indicated under the Related parts tab.
If they have been damaged by the push rods, they must be replaced. We recommend to study the reason for the impact: the choice of push rods may be a cause, the oil channel has been blocked, the push rods do not have the right length etc...
To readjust, you may also need a number of shims, which are listed under the options tab.
