Is this normal for JD60 pushrods?

Hey guys, I've attached a couple pics of the push rods from my John Deere 60 I'm trying to fix. Some of them (mostly the ones on the outside) seem to be slightly bent upwards? Is this normal? And if so, should I go ahead and replace them when I have the head and valves done? Just seems a little odd they are like this so I'm not sure if it's something abnormal or something that is usual with these old 2 cylinders. Thanks.

Sorry guys. Not sure why it's so hard to get pix uploaded to this site. Anyway, they are in the posting thread.
 
They do not appear to be bent to me. I believe what you are looking at is the difference in angle between the pushrod and the tappet adjuster screw, which mate together with a ball and socket joint to allow movement as the rocker arm swings through it's arc.

When you take it apart, keep pushrods in order so they go back where they came from upon reassembly.

One at a time, roll each pushrod on a flat surface and you will be able to see if any are actually bent.
 
Ohhhhh!! Okay, that makes perfect sense then. and yes, I'll do that test by rolling the push rods on a flat surface. Thanks Bob.
 
To keep pushrods in order, it"s common to drill holes in a board and label them. Straight line engine, label which end is front, JD 2 cyl, label left and right.
