what are the heads supposed to be torqued too
60 to 80 pounds i always go 80.
You will want to take a look at a Haynes manual which will show proper torque sequence, usually all are tightened down to a certain point in a certain pattern (usually zigzag or opposite ends of the head) and then finish-tightened down to final torque.
