I'm in the middle of replacing the intake manifold gaskets on my 82k engine and the runners and manifold look pretty awful to me.

The point of this post is to ask what you guys would do? What kind of additives and chemicals would you run in the gas and oil? Is it even something to be concerned about? How about the oil on the mating surface? The two passenger side rearmost bolts were covered in oil when I removed them.
The factory sealant was pretty worn to the point the manifold practically pulled itself off when I loosened the bolts so this job was definitely overdue. I will be replacing fel pro intake gaskets with fuel injector o rings and throttle body gasket as well.

Excellent information from you all. I ended up putting it back together with just a new gasket but down the road I think I'll once again take it off and clean everything up professionally, or even drop in a 5.7.
