Your cart is empty.The popular engine families utilize a positive stop type of rocker arm attachment, which does not allow for any adjustment and consequently there is no consideration for different cam sizes or other modifications to the engine block and heads. COMP Cams has designed a kit to convert this setup to a fully adjustable value train. On the 302-351W Ford, simply remove the standard adjusting nut, slip the spacer over the stuff, install the new nut and adjust the values as necessary.
