I keep breaking rocker arm bolts, help please!

Where did you find 30#

SB rocker bolts are 17-18 ft/lbs or 200 inch/lbs

There was a typo in some of the original service manuals for that torque for a while. I had one where someone corrected it.

I forgot to check the torque, but still don't recommend oiling the bolts before torquing. Clean the threads with taps and dies and run them dry.
