Just to clarify-

110-120 in. oz. is in the same ball park as 12-15 ft. lbs.

If you don't have a torque wrench, use a 3/8" drive rachet and hold it so the rachet part is in your palm, not the handle and tighten it "pretty snug" that way.

These head bolts have been know to pull the metal out of the base if overtightened.

A little too loose will blow a head gasket (big deal) too tight will pull the threads and then you've got a mess.

Botttom line is don't worry about it unless you have a problem or the head needs to come off.
