are the push rod lengths different on a positive stop rocker than the adjustable

What is your question?

i got some heads from a wrecking yard and i should not of when the rockers were on , instead all of them put in a bag breaking the rule of keep them in original location. could that be my issue since these are positive stop rocker studs designed for the rocker nut to be torqued to 20 ft lbs. do i have to buy new rocker assembly to solve my issue. i can get the motor running by attempting to adjust ( loosen ) valve lash.
