Step 10: Repeat the degreeing process on the opposite cylinder bank, this time using the number 6 intake valve
to check the intake centerline. Note that it is not necessary to reestablish TDC in order to verify the #6 intake
centerline.
In the event that your camshaft did not degree in to the camshaft specification, it will be necessary to either
advance (move the cam ahead) or retard (move the cam back) the camshaft to meet the suggested intake
centerline. There a couple of degrees of advance/retard available by loosening the timing gears (lock the
camshafts again before loosening the bolts!) and rotating the crankshaft until the pointer is positioned at the
desired intake centerline reading. Refer back to step 9 if you do not remember how to determine that reading.
Note: When degreeing a cam, remember to look at the degree wheel as two 180 degree sides, no matter
how the degree wheel you are using is marked. Many degree wheels are marked in 90 degree increments.
On wheels that are marked in 90 degree increments, keep in mind that you must continue to count the
number of degrees on past 90 degrees. Be sure all readings are taken from Top Dead Center.
Keep in mind that to advance the cam, you must lower the intake centerline. For example, if your camshaft set
has a lobe separation of 114 degrees, moving the intake centerline to 110 degrees advances the cam 4 degrees.
Conversely, moving the intake centerline to 116 degrees retards the camshaft 2 degrees.
