Spark plugs and Wires:
Check the condition of the spark plugs and wires that you are installing. We
recommend that you start with a new set of AC Delco 44F series spark plugs. In
all our engines we remove the silver gasket ring and use a machine copper gasket
under the spark plug. Check the spark plug gap on each. The threads of the heads
should be clean prior to installation and small amount of anti-seize put on the plug
threads. The spark plugs should screw into the heads most of the way by hand.
Never use a wrench to start spark plugs as the danger of cross-threading is real
high. Torque the plugs to the rated torque.
The firing order of the Engine is marked on our top covers. It is 1-4-5-2-3-6. The
rotor turns clockwise and the Number 1 plug wire should go to the 10 o’clock
position on the cap. It is a good idea to write the firing order on the cap plug
towers to avoid confusion.
Our Spark plug wires are cut to length and labeled to allow for ease of installation.
It is best to route one head at a time and use tie wraps to secure them. Take your
time to insure proper routing around your cooling and other wires. A little bit of
dielectric grease on the plugs aids in protecting the wires from moisture and
corrosion.
