Big block / small block Rocker question

I had the same question, so I compared big block stamped steel rockers on right to small block on left in pictures below.
440 Big Block rockers are significantly longer from push rod indent to valve tip than 318 small block rockers. Also, Distances are different from center of fulcrum to valve tip and push rod indent.
