INSTALLATION
NOTE: Before replacing parts, inspect all related
valvetrain components for damage to prevent
engine misfire.
NOTE: Black valve seals are intake. Brown valve
seals are exhaust.
1. Install valve seals (1).
2. Coat the valve stems with clean engine oil and
insert them in the cylinder head.
3. Install valve spring seats (6).
4. Install valve springs and valve retainers (2).
5. Compress valve springs with a valve spring com-
pressor. Install retaining locks and release tool.
6.If valves and/or seats have been reground,
measure valve tip height (A). Make sure mea-
surements are taken from cylinder head surface
to the top of valve stem.If valve tip height is
greater than 52.96 mm (2.085 in.), grind the valve
tip until within specifications.
7.If valves and/or seats have been reground,
measure installed height of springs (B). Make
sure measurements are taken from top of
spring seat to the bottom surface of valve
spring retainer.If height is greater than 44.45 mm (1.75 in.), install a 0.794 mm (.031 in.) spacer in head
counter-bore under the valve spring seat to bring spring height back to 43.69 - 44.45 mm (1.72 - 1.75 in.).

INTAKE/EXHAUST - VALVES/SEATS/GUIDES
STANDARD PROCEDURE - VALVE AND VALVE SEAT - REFACING
The intake and exhaust valves have a 44.5° - 45° face
angle (1). The valve seats (2) have a 44.5° - 45° face
angle.
Inspect the remaining margin after the valves are
refaced. (Refer to 9 - ENGINE - SPECIFICATIONS).
VALVE SEATS
CAUTION: Do not un-shroud valves during valve
seat refacing.
1. When refacing valve seats, it is important that the
correct size valve guide pilot be used for reseating
stones. A true and complete surface must be
obtained.
2. Measure the concentricity of valve seat using a dial
indicator. Total runout should not exceed 0.051 mm
(0.002 in.) total indicator reading.
3. Inspect the valve seat with Prussian blue to deter-
mine where the valve contacts the seat. To do this,
coat valve seatLIGHTLYwith Prussian blue then
set valve in place. Rotate the valve with light pres-
sure. If the blue is transferred to the center of valve
face, contact is satisfactory. If the blue is trans-
ferred to top edge of valve face, lower valve seat with a 30° stone. If the blue is transferred to the bottom edge
of valve face raise valve seat with a 75° stone.
NOTE: Valve seats which are worn or burned can be reworked, provided that correct angle and seat width
are maintained. Otherwise cylinder head must be replaced.
4. When seat is properly positioned the width of both seats should be 1.02 - 1.52 mm (0.040 - 0.060 in.).

INSPECTION
Va l v e
1. Clean valves thoroughly and discard any burned,
bent, warped, and cracked valves.
2. Measure valve stems for wear (Refer to 9 -
ENGINE - SPECIFICATIONS).
NOTE: Valve stems are chrome plated and should
not be polished.
Valve Guide
1. Remove carbon and varnish deposits from inside of
valve guides with a reliable guide cleaner.
2. Measure valve stem guide clearance as follows:
1. Install valve into cylinder head so it is 14 mm
(0.551 in.) off the valve seat. A small piece of hose
maybeusedtoholdvalveinplace.
2. Attach Special Tool C-3339, dial indicator to cyl-
inder head and set it at right angle of valve stem
being measured.
3. Move valve to and from the indicator. (Refer to 9
- ENGINE - SPECIFICATIONS) for valve guide
specifications. If guides are out of specifications,
ream to next oversize.
3. Ream the guides for valves with oversized stems if
dial indicator reading is excessive or if the stems
are scuffed or scored.
4. Service valves with oversize stems and over size seals are available in 0.15 mm (0.005 in.) and 0.40 mm (0.015
in.) oversize.
NOTE: Oversize seals must be used with oversize valves.
5. Select the correct size reamer to accommodate the oversize valve stem. Refer to Valve Guide Oversize Chart.
6. Slowly turn reamer by hand and clean guide thoroughly before installingnew valve.Do not attempt to ream the
valve guides from standard directly to 0.40 mm (0.015 in.). Use a step procedure of 0.15 mm (0.005 in.) to
0.40 mm (0.015 in.), so the valve guides may be reamed true in relation to thevalve seat. After reaming
guides, the seat runout should be measured and resurfaced if necessary. See Refacing Valves and Valve
Seats (Refer to 9 - ENGINE/CYLINDER HEAD/INTAKE/EXHAUST VALVES & SEATS - STANDARD PROCE-
DURE).
NOTE: Replace cylinder head if guide does not clean up with 0.40 mm (0.015 inch) oversize reamer, or if
guide is loose in cylinder head.
