This shaft-mounted rocker kit for Chevrolet small block with Dart Iron Eagle heads uses 2024 aluminum rockers on an 8620 hardened steel shaft to improve mount rigidity and valve-train stability. Provided in 1.6/1.5 ratios depending on head selection, the system is intended to better transfer cam power to the valves and may require valve cover spacers or aftermarket covers for proper installation clearance.
