When reassembling the cylinders to the crank-
case, it is important to have them properly aligned
so that the cylinder head holes will match up with
the studs. Cylinder head itself can be used to align
the cylinders. Prior to torquing crankcase/cylinder
nuts, install exhaust manifold to properly align ex-
haust flanges or use exhaust flange aligning tool
(P/N 420 8769 02).
Apply Loctite 242 (P/N 413 7030 00) on cylinder
screw threads.
Install and torque screws in a criss-cross se-
quence for each cylinder to 29 N•m (21 lbf•ft). For
454 and 670 engines longer screws go on exhaust
side.
