(f) Mark the front of each cylinder head bolt's head with paint.
(g) Tighten the cylinder head bolts another 90° in the sequence shown in the illustration.
(h) Check that the painted mark is now at a 90° angle to the front.
7. INSTALL CYLINDER HEAD GASKET

(a) Place a new cylinder head gasket in position on the cylinder block.
HINT: The rear side of the cylinder head gasket has marks so that the RH and LH banks can be distinguished. A "3R" mark is on the RH bank's gasket.
NOTE:
Be careful of the installation direction.
