When i used the O74 heads when i drag raced, i always used the longest rocker arm stud i could before it just bottomed out on the stud boss bottom end. Never had issues with cracking a stud boss. Also spring pressures were key too not cracking the stud bosses on the 074 heads. Also used stud gridles helped too.
