is an issue. Stop the process, assess the problem and try again. If
spark plug tubes install successfully, remove the tubes and install the
valve cover. Following valve cover installation, insert the spark plug
tube using the OE O-ring for the spark plug tube seal at the valve cover
interface (not included with heads).
NOTE: The use of these lower spark plug tube O-rings is not
required. Simply remove and discard if not using.
INSTALLATION: Installation is the same as for original equipment
cylinder heads. Consult service manual for specific procedures, if
necessary. Be sure that the surface of the block and the surface of the
head are thoroughly cleaned to remove any oily film before installation.
Use alcohol or lacquer thinner on a lint-free rag to clean. Apply oil or
suitable thread lubricant to head bolt threads and the underside of
bolt heads and washers. Torque cylinder head bolts in three steps
following the factory tightening sequence (See Figure 1).
