Note:
To prevent distortion between cylinder heads
and manifolds, we recommend the following
steps :
● Refit cylinder heads using guidance bolts.
● Oil the new cylinder head bolts and their rest
surface with "Optimoly Withe T" paste.
● Hand tighten new cylinder head bolts.
● Mount rectified ruler (Special tool) onto the
exhaust side. Tighten screws at 20 Nm. If no
ruler is available, fit exhaust pipe and tighten at
20 Nm.
