Head Bolt Replacement

[Buicksandrail]

Do I need to replace the head bolts when doing the head gaskets. The block has studs on one side and bolts on the other.

Thanks,

Trent

Torque specs will be different, otherwise I see no problem with that. Bolts 85 ft-lbs, studs 65 ft-lbs. GB

If they are the factory installed "torque to yield" head bolts, those are a one time use and need to be replaced. ARP offers a very good replacement for head bolts.

While Audiowizard makes a good point, torque to yield bolts were not used on our earlier engines. GB

Even thou they did not use the torque to yield bolts on the early cars, I would still replace the bolts. JMHO
