The ARP rocker arm stud kit for small-block Chevy includes 7/16-inch studs across the set, intended to replace factory hardware where that diameter is required. By providing the full complement of 7/16-inch studs, the kit helps maintain rocker arm alignment and consistent clamping, making valvetrain maintenance and reinstallation more straightforward for SB Chevy engines that specify 7/16-inch studs.
