You tighten the bolts in sequence first to 22 ft-lbs then again in sequence to 33 ft-lbs. Lastly using a torgue angle gauge you tighten an additional 90 degrees in sequence.

Good luck and let us know. :)

You are using new head bolts? They stretch to obtain proper torque.

Suggested Repair

Tighten the cylinder head bolts in sequence to 22 ft-lbs, then again in sequence to 33 ft-lbs, then an additional 90 degrees in sequence with a torque-angle gauge. Use new head bolts, since they stretch to achieve the proper clamp load.

Conversation Summary

The owner of a 1997 Saturn SL SOHC 4-cylinder asked for the torque specification for the bolts attaching a new cylinder head to the engine, after being told a guess of 50 lb. An expert advised tightening the bolts in sequence to 22 ft-lbs, then 33 ft-lbs, followed by an additional 90 degrees with a torque-angle gauge, and noted that new stretch head bolts should be used.
