The cylinder head bolt torque is a 2 step process.
First: Torque all of the bolts to 45 Nm (450 Kgf-cm or 33 ft lbs.)
Replace any head bolt that will not torque to the above specs.
Second: after all ten bolts are torqued to the above specs, the head bolts are then "Torqued to Distance"...
Starting at the center bolts, retorque all ten bolts an additional 90 degrees.
Hope this helps, the graciousness of a FixYa rating would be greatly appreciated.

Hello vienotkelly: The correct Main bolt torque is 42 foot pounds. The connecting rods torque to 29 foot pounds. The torque sequence for the head bolts and the correct way to tighten the bolts are attached to this reply. Thak You for using FixYa. Roger

Tighten in several passes to 44 foot pounds.
I just wanted to add. Since this is an aluminum cylinder head, I hope you loosened the head in the loosening torque pattern. The pattern opposite of the torque tightening pattern. If not, you stand the chance of warping the head.
Again, since it's an aluminum head, it needs to be checked for flatness. Most aluminum heads need to be surfaced before re-installing.
Tightening torque pattern is as follows:
1.The Drivers side of the engine is the Left side.
From the Front going towards the back; the bolts are numbered 10, 6, 1, 3, and 7.
From the Front going towards the back on the Passenger side; the bolts are numbered 8, 4, 2, 5, and 9.
The Exhaust and Intake Camshaft Bearing Cap bolts go to 9 foot pounds. Tighten gradually. One bolt to the other with so many foot pounds, work back, and forth up to 9lbs.
Camshaft Timing Pulley bolts go to 43 foot pounds. (In a tightening sequence, and gradually)
