The keepers must be located in the groove closest to the tip of the valve. Any other groove will yield the incorrect installed height and may

cause premature valve train failure. S&S is not responsible for incorrect installation. Consult an S&S dealer or S&S Sales Representative if

you have any doubts as to the correct installation of this product.
