This is a rare set of Holroyd hand machined BBC rocker studs, balls & adjuster nuts, these were a 'must-have' item for NHRA 'Stock' cl*** race engines and were on the B/S National Record holder until roller rockers were allowed. This is for a full set of 16 including the BBC rocker and shipping to lower 48. For those of you running a bigger valvespring on a street motor you can't go wrong with these, they are m***ive. Thanks for looking, Oj
