tween the guide bushing and valve stem.
11. INSPECT AND GRIND VALVES
(a) Grind the valve enough to remove pits and carbon.
(b) Check that the valve is ground to the correct valve face
angle.
Valve face angle: 44.5°
(c) Check the valve head margin thickness.
Standard margin thickness:
1.0 mm (0.039 in.)
Minimum margin thickness:
0.5 mm (0.020 in.)
If the margin thickness is less than minimum, replace the valve.
(d) Check the valve overall length.
Overall length:

Exhaust95.15 mm (3.7461 in.)
94.90 mm (3.7362 in.)
Minimum Intake
Exhaust94.60 mm (3.7244 in.)
94.40 mm (3.7165 in.)
If the overall length is less than minimum, replace the valve.

12. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats. Re-
move only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a thin coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate the valve.
(c) Check the valve face and seat for these:
If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.
If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
Check that the seat contact is in the middle of the
valve face with these width.
1.0 − 1.4 mm (0.039 − 0.055 in.)
If not, correct the valve seats as follows:
(1) If the seating is too high on the valve face, use 30°
and 45° cutters to correct the seat.
(2) If the seating is too low on the valve face, use 60°
and 45° cutters to correct the seat.
(d) Hand−lap the valve and valve seat with an abrasive com-
pound.
(e) After hand−lapping, clean the valve and valve seat.

If the journal diameter is not as specified, check the oil clear-
ance.
17. INSPECT CAMSHAFT BEARINGS
Check the bearings for flaking and scoring.
If the bearings are damaged, replace the bearing caps and cyl-
inder head as a set.
18. INSPECT CAMSHAFT GEAR SPRING
Using vernier calipers, measure the free distance between the
spring ends.
Free distance:
18.2 − 18.8 mm (0.712 − 0.740 in.)
If the free distance is not as specified, replace the gear spring.
19. INSPECT CAMSHAFT JOURNAL OIL CLEARANCE
(a) Clean the bearing caps and camshaft journals.
(b) Place the camshafts on the cylinder head.
(c) Lay a strip of Plastigage across each of the camshaft jour-
nals.
(d) Install the bearing caps (See page EM−51).

Maximum oil clearance:
0.10 mm (0.0039 in.)
If the oil clearance is greater than maximum, replace the cam-
shaft. If necessary, replace the bearing caps and cylinder head
as a set.
(g) Completely remove the plastigage.
20. INSPECT CAMSHAFT THRUST CLEARANCE
(a) Install the camshafts (See page EM−51).
(b) Using a dial indicator, measure the thrust clearance while
moving the camshaft back and forth.
