Sealant for intake pitted around coolant passages?

I'm about to install the lower intake onto some new heads. It looks like the last guy used some sealant on the intake around the coolant passages. They are a bit pitted. Truth is, most of the pitting isn't on the surface where the gasket will seal. Still, I'm concerned about a water tight fit.

Any suggestions on what I might use? I've got a fresh set of gaskets and would feel a little more comfortable with some additional assurance. I've got Toyota FIPG but I'm not certain that would be the best option. In fact it might be exactly wrong for all I know.

 

Really hard call to make with no pictures .

 

Here's a picture of the worst one. My question was more about *which* sealant is most appropriate. I've got black fipg on hand. I wonder if some particular RTV would be better? Ultra gray was recommended by one user here. It's almost comical how many different varieties of RTV there are.

 

I wouldn't combine sealant and gasket. That's just asking for issues. Just use the gasket. It should seal fine, but if it bothers you go get a couple mils machined off.
