Notes:
♦ Always replace cylinder head bolts.

♦ Always replace seals and gaskets when car-
rying out removal and installation operations.
♦ If a reconditioned cylinder head with the cam-
shaft installed is fitted, it is necessary to oil
the contact surfaces between bucket tappet
and cam track after installing the cylinder
head.
♦ The plastic bases supplied as a protection
for the open valves must not be removed until
just before fitting on the cylinder head.
♦ If the cylinder head is replaced, the entire
system must be filled with fresh coolant.
♦ Cylinder heads with cracks between the
valve seats or between a valve seat ring and
the thread of a spark plug, can continue to
be used without any reduction in life provided
these are slight incipient cracks which are
not more than 0.3 mm wide, or only the first
4 turns of the spark plug thread are cracked.
