12 CYLINDER HEAD ASSEMBLY
21 Release the cylinder head setscrews evenly
and gradually in the reverse sequence to that
shown in (A or B). Check the setscrews for
distortion with a straight edge (C1) held along the
setscrew (C2). If there is a visual reduction in the
diameter of the thread (C3) that has not been in
engagement with the cylinder block, the setscrew
must be discarded.
Caution: Do not use a lever to separate the
cylinder head from the cylinder block.
22 Remove the cylinder head and put it on a
surface that will not damage the face of the cylinder
head.
