I am having some tuning issues and want to make sure that my timing marks line up. What is the easiest, least involved way (if any)
to do this?

Thanks

take the timing cover off and use a straight edge of some sort, there are 2 marks on each cam gear. they should be in a fairly straight line, the 2 middle marks should be very close to the straight edge but are usually a little higher or lower.

yeah no problem, another big thing to is making sure your on the right timing mark, intake or exhaust stroke. the cams should be marked.

With everything still assembled jack the car up or just crank the wheel so you can get a 1/2 ratchet on the crank. Pull the upper timing cover off if its not already. Turn the engine over by hand and watch or have someone else watch for the small white notch on the inside edge of the harmonic dampner to come up. This is the mark you see when using a timing light to set base ignition timing. On the timing tab that's apart of the timing cover you have 10*btdc 5*btdc and 0. Line that white notch up with the 0. Check that the dowels on the cams/cam gears are pointed up. If not turn the engine over till they are and the white notch lines up with 0. Then check that the notches on the cam gears line up together in the center. If so your good.
