Here is the spec for 1977 through 1984 on
the Ford 300 or so called now the 4.9 engine:
Cylinder head
bolts: 70-75 lbs. The sequence is driver's side starting on bolt one (fifth bolt
in line of bolts or center of line of bolts) and going straight across to bolt 2
on passengers' side and then to the side of bolt 2 is bolt 3 and back across to
bolt four to the right of bolt 1. This is done in a zig -zag pattern until all
bolts are torqued to recommended torque.
