So don't retorque it? The headgasket has been replaced with a metal one, and set to factory torque settings, (like 50) they should be at 70ish according to: Changing Headgasket On 87 Supra Turbo "Torque the head bolts down to 72 ft/lb. YES! This is what causes BHGs in the first place. The factory torque setting for the head bolts is TOO LOW! They specify 54 ft/lb. if you torque down to this level, your new head gasket will last all of 6 months then you will be back to square one. Torque it down to 72 and you will never have any more problems." and for bad wiring... what are some things to look for, or replace to prevent future problems? |

If you know for sure its a metal one and the head and bottom block was machine correctly.
Then I guess re-torquing it would be fine.
