COMP Cams - 4610-16
Rocker Arm Nut - 5/16-24 in Thread - Conversion to Adjustable - Steel - Black Oxide - Small Block Ford - Kit
This 4610-16 adjusting nut kit includes a set of 16 washers and nuts to convert your Ford 302 and 351 Windsor rockers to an adjustable valvetrain. Fits 5/16" studs.
Many of 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. For that reason, COMP Cams has designed a kit to convert this setup to a fully adjustable valve train. On the 302-351W Fords, simply remove the standard adjusting nut, slip the spacer over the stuff, install the new nut and adjust the valves as necessary.
