Hi do you need to re tighten ARP head nuts Studs on a 3.2 after run in?
If so do i slacken off one nut at a time and re torque? Or do i just test the torque? Thanks John Last edited by slow car; 12-01-2014 at 12:16 AM.. |

This is what is on ARP site, but it is generic for all engines .In the past i have had Porsche heads come loose so i am wanting experts advise based on facts about air cooled 911 engines.
John Do I need to re-torque my head bolts or studs? If you follow the ARP installation instructions, there should be no need to do a re-torque. However, it may be necessary under certain circumstances if the gasket manufacturer’s instructions require it, particularly if a fire ring has been installed. ARP recommends not doing a re-torque on a hot engine. |
