    will these rockers work on a 1995 lt1 one with aluminum heads

    Asked by: sonoma
    No, you would want a self-aligning roller rocker for that application.

    Asked by: 83k10chevy
    These are not able to be used in a Vortec application as they are not self aligning rocker arms.

    Are the rockers self aligning? Will they work on Cast iron Vortec heads?

    Asked by: Pdunner
    This part number is not self-aligning and will not work with cast iron vortec heads without modification. The correct part number you need is either 778-66915C or 778-66914; the difference between the two is the ratio.
