Putting head on slant six

Valve seals installed. Rocker arm shaft and rockers installed. Do the rocker arms correlate to specific valves? I threw them all in a bucket to degrease and reinstalled as if they were universal.
The push rods that came with the car aren’t all the same. There are three types.
Three of the ones on the left with a larger ball end and rounder cupped rocker end.
Seven of the middle smaller ball end.
Two with a rounded off end with no ball at all. Any help here? Hope whatever lifters are in block will make this clear on installation...
