You have factory non-adjustable rocker arms.The threads,both ends,should be metric.I do not know of any aftermarket suppliers,an engine builder or junk yard might be the fastest. The GM # is 10044997 for the stud,I did not look up the nut,it is 8mm,and Melling makes replacement nuts.As copper said,you want to clean up those threads in the head before putting new one in.It should be 10mm,but I forget the pitch.
