Head bolt torque is 15 - 18 ft-lbs. Tighten bolts in 4 ft-lb increments. Tightening sequence is: 3 o'clock, 11 o'clock, 6 o'clock, 12 o'clock, 5 o'clock, 7 o'clock, 1 o'clock. There is no 9 o'clock bolt, at least not on my engine. Remember to clean head and cylinder gasket surfaces thoroughly, and also check for cylinder head warpage. Lay head on a precision flat surface and make sure that warpage is no greater than .005 inches. A machine shop can easily do this for you if you prefer.
