So I called AFR this morning to find out the max torque for my cyl head bolts, they told me to call Fel Pro, and they told me to call ARP. ARP says 75 ft lbs with sealer. 85 ft lbs with oil.
That's not what surprised me. Before I hung up with Fel Pro he told me to make sure to torque the head bolts in a 3 part process:
1) First take them to max torque.
2) Then, BREAK THEM 1/2 A TURN LOOSE ONE AT A TIME, then take them back to max torque.
3) Then go through one heat cycle, and retorque. Has anyone heard of this before? He said it's to flatten out the gasket.
