require an initial torque and a final torque
sequence. Later engines with press-in-place
gaskets require only a final torque.

following sequence in lower illustration. Tighten two
longest cap screws located next to crankshaft center
line. Then, go to bottom cap screws (alternating from
side-to-side) and tighten remaining cap screws to
specifications.
