NOTE: Cylinder heads are retained using either hex

flange screws or hex flange nuts and washers

on studs. Do not interchange or mix

components, as the cylinder heads may have

different machining, unique to each fastening

method.

1. Remove the four hex flange screws or hex nuts

and washers securing each cylinder head. See

Figure 9-42. Discard the screws or nuts and

washers once removed. Do not reuse. Studs (if

present) should only be removed if damaged or if

cylinder reconditioning is necessary. Once

removed, they must be replaced.

intake or exhaust and cylinder 1 or 2. Push rods

should always be reinstalled in the same

positions.
