As per the manual page 101 of 230 the 4 bolts that hold the head to the cylinder and bottom of engine are torqued to 27.5 foot pounds.
The cylinder bolts like 12a and others are torqued to only 7 foot pounds.
So it would make sense why they broke on us. I didn't use a torque wrench when mine broke, but definitely used more than 7 or 20 trying to tighten.
