Reply To: 1934 8 cyl. head torque specs

Greg,

8 cylinder head torque has been documented in several of the PAS Service Bulletins, 95-2, page 2, for example. If you don’t have a copy, let me know and I will e-mail it to you.

The torque should be 65-70 ft-lb, however:

1. The bolts should be tightned following the recommended sequence in the PASB.

2. The bolts should be tightened in stages, don’t just take them right to the 65-70 ft-lb limit.

3. Head bolts should be tightened on a cold engine.

4. After the engine has been run, the gasket compressed, and everything stabilized, the head bolts will again need to be re-torqued.
