Pushrod length

Well, after pulling the rocker shafts and doing some measuring it looks like I need new pushrods. Number 1 cylinder exhaust pushrod is definitely worn more than the others. The cup end was .010 deeper than the intake push rod. The ball end looked more worn also. I couldn't get and accurate length measurement, because I don't have large enough set of calipers. With a tape measure I can see a bit of a difference in length. I also checked to make sure it wasn't bent and I'm good there.

That was also the valve with the bottomed out adjuster. I guess after 55 years it's time to replace them all.
