    Why do all of the manuals say you have to mark each pushrod and lifter and reinstall them in the same location?

    I would guess it has to do with the way parts ware/brakein period of new parts together. You wouldn't want to reware/rebrakein the parts.?? Just a guess...

    yeah all to keep same wear spots together, like if you are doing new head gaskets or something then you would want to replace all the rods and lifters back in same locations they were in before you started.

    I don't understand the pushrods part unless they are bent or clogged inside, or you had some other You can put the pushrods in a drill press and you will easily tell if they are bent or not.

    The cam0lobes are angled so they twist the hydraulic flat-tappet lifters. If these break-in incorrectly, premature cam-lobe and lifter result. So if you put a lifter on a different lobe (especially a left bank to a right bank) the wear will be incorrect, and can cause premature cam-lobe/lifter wear. This results in a flat cam.

    Good luck.
