102 Head Bolts are TORQUE TO YIELD, which means they TORQUED in DIFFERENT STEPS and then ANGLE ROTATED a certain amount of DEGREES to STRETCH them.
The MANUAL has a SPECIFICATION for measuring them to determine if they are RE-USABLE . . .
If the engine was OVERHEATED . . . REPLACE THEM ALL . . . PERIOD ! ! !
TIP: ALWAYS use the specs on the SHEET that comes with the set, if you're using AFTERMARKET gaskets . . . If you're using FACTORY gaskets, there may NOT be any specs with the set. If so, you NEED to get CURRENT specs, as they've been updated along with the gasket designs . . .
