1998 chevy: tightening..head bolts..up, 350 small block engine..30 ft

Customer Question

when tightening the head bolts on my 1998 chevy pick-up, 350 small block engine, what torque setting should I be using? I've been advised that it's 30 ft. lbs. of torque, but I keep twisting off the bolts. Is there another setting I should be using?

Did you install new bolts when doing this job?
Customer: replied 7 years ago.
yes, brand new.

You may want to try a different torque wrench because the max torque is actually 65 ft lbs and the bolts should hold up much higher than that. Torque settings below, ft lbs on the left and N.m on the right

No it is not as shown in the pic the heads should be tightened down in 3 passes, the first pass is 24 ft lbs the second pass is 45 ft lbs and the third pass is 65 ft lbs.
