    Thanks for clearing that up.

    Is there any advantage/disadvantage to cast vs stamped in replacing them?

    The 67/69 are a good rocker assembly if in good shape, but most the time the stamped are fine for single spring applications

    They seem to be the most available, and I don't plan to ever have any huge cam in it. Hoping the lazy lifter is just gunked up and a cleaning out fixes it, I fear the can of worms a cam issue could open up. Mostly bad cam bearing(s) requiring the engine to be pulled.
