Fig.: Cylinder head bolt torque sequence-2.2L engine
Apply a coating of 1052080 or equivalent sealer to the cylinder
head bolt threads. Install the cylinder head bolts (within 15 minutes of
sealer application), then tighten them in the proper sequence first to a
torque of 46 ft. lbs. (63 Nm) for long bolts or to 43 ft. lbs. (58 Nm)
for short bolts and then tighten all bolts an additional 90 degree turn
using a torque angle meter.
Hope this helps (remember to rate this answer).
