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.
yes they were both cracked
Ok! But do they look the same where the rocker arm studs go into the head?
no, but why can you not use either. i can not find any other part in the 4.3 engine that is different. is it not just one type the non adjustable better than the adjustable.
