LIM Screens
I have been working on cleaning my engine parts for paint and in several of my lower intake manifolds, I noticed the screens that are below the injectors inside the mani are somewhat rusted or in bad shape. Is there any way to fix these or can they be cut out? I assume they are there to help atomize the fuel better.

Try buying NA manifolds, people sell them cheap. I found these pieces still stuck inside the runners, and just what I needed. 
They are pricey for such a silly piece of plastic, but fortunately you don't need too many, so just buy them if you must.

There HAS to be a way to recreate them using aluminum. I don't see how you cant spec them out top side, make the o-ring and cut the aluminum "stands" to hold an aluminum disk. I mean, look at how they are shaped. Maybe I am myopic and stupid, but I bet I could make a replica in a days time. They are so simple.
I am not trying to dump on the OP, I am dumping on the aftermarket manufacturers. Even if you made a piece to seal the injector without the little fuel diffuser, how hard can that be really?

They can be removed very carefully if you liberally soak the area in carb cleaner, then penetrating oil and carefully rock them back and forth using a piece of rod that fits into the hole. I almost always break at least one of them, no matter how careful I am.
In many cases it is less of a headache to just leave them in place and clean them out with carb cleaner.
