4. Place the new head gasket over the cylinder head studs
on the block. Be sure the TOP mark
(Figure 13) on the
gasket is up.
5. Carefully lower the head onto the cylinder block.
6. Apply engine oil to the threads on the cylinder head
studs.
7. Install and tighten the cylinder head retaining nuts fin-
ger-tight.
8. Tighten the nuts and bolts following the sequence
shown in Ftgurc 14 to the torque specified in Table 4.
Tighten the nuts and bolts in three equal steps until reach-
ing the final torque setting.
9. If removed, install the sacrificial anode into the cylin-
der head.
10. Attach the oil line fitting
10 the cylinder head.
II. Install the push

I. Make sure the cylinder head and block gasket surfaces
are clean.
2. Recheck all visible oil and water passages for cleanli-
ness.
3. Apply Three Bond 50 gasket scaler to both sides of a
new cylinder head gasket.
6. Clean away
all carbon on the piston top.
7. Check the cylinder head studs for damage and replace
them
if
necessary, Ir a stud is loose, tighten itusing the fol-

typical.
b. Rotate the nuts so they contact each other. then hold
onc nut and lighten the other nut against the first
nut.
c. Tighten the stud in the cylinder block by turning the
top nut until reaching a torque of 60
Nom
(44
ft.-lb.).
d. Hold the bottom nul, loosen the top nut, and remove
both nuts.
8. Check the threaded rocker ann support stud for dam-
aged threads. Replace if necessary.
9. Check
for warpage of the cylinder head-to-block gas-
ket surface with a straightedge and
feeler gauge (Ftgure
12). Measure diagonally, as
well as end to end. If the gap
exceeds 0.07 mm (0.003 in.). have the head resurfaced by
a machine shop.
