    I'm ready to install the cams after a top end rebuild. I asked this Question before, shame on me. with the
    ignition tdc indicator set, which pistons should be up ? #1 & #4 or #2 & #3 ? Also, I got the cams mixed up.
    One of them has a worm gear to the right of the sprocket is that one the exhaust or intake ?

    Worm gear is exhaust side, that gear drives tachometer if equipped with cable style tach.

    Thanks. I'm also reinstalling the cylinder head today. I got a big pack of gaskets. The big ones are obvious
    but I'm wondering if there is a diagram somewhere showing where all the seals and "0" rings go?
