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)

If you have a vehicle application for the motor you can get a Haynes or Chilton manual from your local auto parts store. They usual run around $30.
