ARP Top of the line quality rocker arm adjusting nut with polyloc . I had Comp Cams nuts but they started backing off . These end that problem .

These are great if you have some rocker arms with crap nuts. Be careful using red thread locker. I had to heat them up to get them off. I'd say the threads are more precise than normal nuts. Switched to blue just in case.
