About This Product
Kibblewhite Precision Machining valve spring spacing shims compensate for height changes during cylinder head assembly. Machining seats or fitting new valves alters the installed height. These shims bring the springs back to spec and stop premature fatigue. You will need a height mic to check each spring individually. Stack or remove shims until the pressure is even across all valves. This keeps the valvetrain stable and the engine reliable under load.
