My tune-up went something like this:

1. One entire can of Valvoline Synthetic carb/throttle body cleaner, sprayed down the carb (running of course).
2. One can of Seafoam into the intake manifold through vaccum line (running).
3. New Distributor Cap
4. New Distributor Rotor
5. New Spark Plug Wires
6. New Spark Plugs (I prefer NGK)
7. New Fuel Filter
8. A Bottle of Redline Fuel System Cleaner mixed with a full tank of Cheveron Supreme
9. Adjust the timing. Mine is advanced about 2-3 degrees above stock (set @ 5 BTDC).
10. Engine Flush and Oil Change.

Don't add any fuel until driving to a 1/4 or below, or you'll just waste your Fuel System treatment. I noticed a considerable difference in the way the truck performed after doing this tune-up. She ran smoother, pulled better under acceleration, idled smoother, and was easier to start. I recommend these fuel system cleaners. Redline, Duralube, Slick50, Valvoline, Berryman's B-12 Chemtool, and Greased Lightning. I also did a chemical flush and back-flush on the cooling system. I didn't add it on the tune-up list because that's a long interval maintenance item. One thing I didn't do at that time was adjust the valve lash. I did do that later on, and the engine smoothed out even more (I clearanced the lash a "thingy hair" tighter than factory spec too).

Note: I can testify to the effectiveness of my method of intake/fuel system cleaning. It does work. About 2 weeks later, I replaced my head gasket. In the process of doing such I inspected the intake ports. They were extremely clean by any standards. Although, there is no hope for the carbon that gets caked on the pistons. However with regular useage of fuel system cleaners on a fresh engine, carbon build-up on pistons should be kept at a minimum.
