Push Rods which one?
your going to have to get a pushrod length checker. every engine is different. you need to set up the #1 valvetrain with the the checker at zero lash and 2 threads showing on the bottom of the rocker arm lash adjuster. then lock down the checker rod and then pull it out and measure. This is critical to proper valve train geometry. if the push rod is too short and the adjuster is hanging way out then it throws the geometry way off and will most often snap the adjuster ball off.
this was mine with a too short push rod. notice how the angle looks goofy.
this is with the new correct push rods.
