For a stock application, stock rockers and adjusting screws are fine. It is
normal for the adjusting screws to become faceted.
Anyway, either with the Berg adjusting screws you would have to check valve
clearances on every oil change, to motitor exhaust valve stretching. In case
you decide to install them, keep in mind that you should keep the stock
valve geometry, and to do this you will have to grind the rocker arms. Do
not put spacers under the rocker towers.
