    I'm using a set of vortec heads on an old four bolt main and was wondering if anyone knew for sure if they require a different kind of pushrod?

    Thanks,
    John

    No, standard length 7.800" long. JUST as long as you don't have a roller cam. The push rods don't change, just the rockers to a self aligning style.

    Displacement, cubes, and did you say you drive a riceburner???

    Thanks guys. I went out an bought a set of comp cams pushrods. I looked over the rockers and saw one odd duck, it wasnt self aligning. Looks like we should have been more careful when we were grabbing rockers. I have a replacement now though. I am getting so excited about dropping this motor in.
