IMPORTANT: ALWAYS thoroughly inspect new
cylinder head gasket for possible
manufacturing imperfections. Return
any gasket that does not pass
inspection.
Be sure cylinder head and block gasket
surfaces are clean, dry, and free of any
oil.
Installing Cylinder Head
1. Put a new head gasket on cylinder block. Do not use
sealant on gasket; install dry.
IMPORTANT: If cylinder head is lowered onto cylinder
block and the head is not positioned
correctly on locating dowels, remove
cylinder head and install a new gasket.
DO NOT try to reposition cylinder head
on the same gasket again since the fire
ring may possibly be damaged.

using appropriate lifting equipment. Make sure that
head is positioned correctly over dowels and sits flat
