Installation

(1) Coat valve stems with clean engine oil and insert them in cylinder head.
(2) If valves or seats have been reground, check valve tip height (A).
Make sure measurements from cylinder head surface to the top of valve stem.
(3) Install valve seal/spring seat assembly over valve guides on all valve stems. Ensure that the garter spring is intact around the top of the rubber seal. Install valve springs, valve retainers.








(4) Compress valve springs with a valve spring compressor install locks and release tool.
Cylinder head bolts should be carefully examined BEFORE reuse. If the threads are necked down the bolts should be replaced.
Necking can be checked by holding a scale or straight edge against the threads. If all tine threads do not contact the scale the bolt should be replaced.
(5) Before installing the bolts the threads should be oiled with clean engine oil.

(6) Tighten the cylinder head bolts in the sequence shown in the figure.
Using the 4 step torque turn method, tighten according to the following values:

Step 1: Tighten center fasteners 1 thru 6 to 33 Nm (24 ft. lbs.) Then outer fasteners 7 thru 10 to 28 Nm (20 ft. lbs.)

Step 2: Tighten center fasteners 1 thru 6 to 67 Nm (48 ft. lbs.) Then outer fasteners 7 thru 10 to 28 Nm (20 ft. lbs.)

Step 3:Tighten center fasteners 1 thru 6 to 67 Nm (4 ft. lbs.) Then outer fasteners 7 thru 10 to 28 Nm (20 ft. lbs.)

Step 4: Turn all fasteners 1 thru 10 1/4 turn (90 degrees). Do not use a torque wrench for this step.

Note: The four short bolts are placed in the corners.

Step 1
Torque all center bolts to 34 Nm (25 Ft Lbs), Torque the 4 corner bolt to 27 Nm (20 Ft Lbs)
Step 2
Torque all center bolts to 68 Nm (50 Ft Lbs), Torque the four corner bolts to 47 Nm (35 Ft Lbs),
Step 3
Re-torque all center bolts to 68 Nm (50 Ft Lbs), Re-torque the 4 corner bolts to 47 Nm (35 Ft Lbs).
Step 4
Tighten all bolts in the Specified sequence an additional 90° (1/4 turn).
