Edelbrock hardened guide plate kit part #9669 is made from high‑grade alloy steel and hardened to 60 Rockwell C. The stepped plates support pushrods closer to the rocker arms, stabilizing them and helping maintain valvetrain alignment for AMC engines from 1966–1991. Supplied in sets of eight, these guide plates are intended where improved pushrod guidance and rocker stability are required to preserve consistent valvetrain operation.
