    Have a 350 with the intake off and would like to know if there is a test I can do to one, two or all to determine if they're bad.

    I take them out and make sure they are flat on the bottom, not concaved in.

    I was thinking mainly about the internals- wore out spring etc.

    This is my method:
    If you pull it out and it comes out in little peices or you find it in the bits on the bottom of your pan then you know its bad! /forums/images/graemlins/rotfl.gif

    Actually that's not true, they're supposed to be convex, slightly.

    if they have any wear that doesn't look natural like pitting or scoring, i'd say its bad.

    I'd do the cam and lifters as a unit--haven't had much luck putting new lifters on an old cam,even when the lobes looked ok.Every small block I've had needed a cam so far,with only one or two exceptions--they had new cams installed before I got them!.You can get a cam and lifters for under 100 bucks--its worth it!.
