(e) Select a new guide bushing (STD size or O/S 0.05).
If the bushing bore diameter of the cylinder head is greater
than 11.027 mm (0.4341 in.), machine the bushing bore to
the following dimension:
Rebored cylinder head bushing bore dimension:
11.050 ± 11.077 mm (0.4350 ± 0.4361 in.)
If the bushing bore diameter of the cylinder head is greater
than 11.077 mm (0.4361 in.), replace the cylinder head.
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
°
(f) Gradually heat the cylinder head to 80 ±100°C 076
± 212°F).
(g) Using SST and a hammer, tap in a new guide bushing
until the snap ring makes contact with the cylinder
head.
SST 09201±70010
(h) Using a sharp 6 mm reamer, ream the guide bushing
to obtain the standard specified clearance (See
page EM±86) between the guide bushing and valve
stem. (d) Using a caliper gauge, measure the bushing bore di-
ameter of the cylinder head.

(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 the following:
wIf blue appears 360° around the face, the valve is con-
centric. If not, replace the valve.
wIf blue appears 360° around the valve seat, the guide
and face are concentric. If not, resurface the seat.
wCheck that the seat contact is in the middle of the valve
face with the following width:
1.0 ± 1.4 mm (0.039 ± 0.055 in.) (d) Check the valve overall length.
Standard overall length:
Intake 96.1 mm (3.783 in.)
Exhaust 96.2 mm (3.787 in.)
Minimum overall length:
Intake 95.6 mm (3.754 in.)
Exhaust 95.7 mm (3.768 in.)
If the overall length is less than minimum, replace the
valve. (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.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a
grinder or replace the valve.
NOTICE: Do not grind off more than the minimum.
12. INSPECT AND CLEAN VALVE SEATS
(a) Using a 455 carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.

B. Inspect cam lobes
Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
Intake 39.510 ± 39.610 mm
(1.5555 ± 1.5594 in.)
Exhaust 38.960 ± 39.060 mm
(1.5339 ± 1.5378 in.)
Minimum cam lobe height:
Intake 39.36 mm (1.5496 in.)
Exhaust 38.81 mm (1.5279 in.)
If the cam lobe height is greater than maximum, replace the
camshaft.
C. Inspect camshaft journals
Using a micrometer, measure the journal diameter.
Journal diameter: 26.949 ± 26.965 mm
(1.0610 ± 1.0616 in.)
If the journal diameter is not as specified, check the oil clear-
ance. 14. INSPECT CAMSHAFTS AND BEARINGS
A. Inspect camshaft for runout
(a) Place the camshaft on V±blocks.
(b) Using a dial indicator, measure the circle runout at the cen-
ter journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the
camshaft. (c) Using a spring tester, measure the tension of the valve
spring at the specified installed length.
Installed tension:
18.6 ± 21.4 kg (41.0 ± 47.2 1b, 182 ± 210 N)
at 33.8 mm (1.331 in.)
If the installed tension is not as specified, replace the
valve spring.
D. Inspect camshaft bearings
Check the bearings for flaking and scoring.
If the bearings are damaged, replace the bearing caps and
cylinder head as a set.

(c) Using a plastic±faced hammer, lightly tap the valve
stern tip to assure proper fit.
3. INSTALL VALVE LIFTERS AND SHIMS
Check the valve lifter rotates smoothly by hand.
