What do you consider "overheating"? The gauge reading higher than normal light coming on or is it actually boiling over? Do you hear the cooling fan come on when it starts to heat up? How fast does it get hot? Does it seem to cool down if you are moving? Any white smoke out the exhaust?
A tune up on that engine is basically plugs and adjusting the valve clearance. The valves could make a small change but if it is actually overheating they will not do much for that.
