Cylinder Head Torque Analysis:

Install cylinder head with new gasket.
Be sure to install washers between bolts and cylinder head.
Do not rotate crankshaft and camshaft separately, or valves will strike piston heads.
Apply new engine oil to cylinder head bolt threads and seat surfaces.
Tighten bolts (1) to (10) in numerical order using the following procedure:

a. Tighten bolts to 29.4 Nm (3.00 kg-m, 21.69 ft. lbs.).
b. Tighten bolts to 58.8 Nm (6.00 kg-m, 43.37 ft lbs).
c. Loosen bolts completely.
d. Tighten bolts to 29.4 Nm (3.00 kg-m, 21.69 ft. lbs.).
e. Turn bolts 50 to 55 degrees clockwise. If angle wrench is not available, tighten bolts to 53.9 to 63.7 Nm (5.50 to 6.50 kg-m, 39.76 to 46.99 ft lbs).
f. Tighten bolts ((11) to (15)) to 6.3 to 8.3 Nm (0.64 to 0.85 kg-m, 55.8 to 73.5 inch lbs).

Applying Liquid Gasket:

Camshaft Cap Torque Sequence:

Install camshaft brackets and distributor bracket.
Make sure camshaft brackets are aligned as shown in figure.
Refer to marks made at disassembly to ensure camshaft brackets are installed in their original positions.
Apply liquid gasket to distributor bracket as shown in the figure.
Apply new engine oil to bolt threads and seat surfaces
Tighten camshaft bracket bolts using the following procedure:
a. Set camshafts and camshaft brackets.
b. Tighten bolts (11) to (15), then (1) to (10): 2.0 Nm (0.204 kg-m, 17.7 inch lbs.)
c. Tighten bolts (1) to (15): 5.9 Nm (0.60 kg-m, 52.2 inch lbs.)
d. Tighten bolts (1) to (14): 9.0 - 11.8 Nm (0.92 - 1.20 kg-m, 6.7 - 8.7 ft. lbs.)
e. Tighten bolt (15): 6.3 - 8.3 Nm (0.64 - 0.85 kg-m, 55.8 - 73.5 inch lbs.)
