The heat shield will rust through beneath the bolts.....all will be well without it anyway.
The bit beneath is the exhaust manifold and that will be rusty too.....they all are. It won't rust through though so forget about that one!

the heat shield itself might not be rusty, it is probably the steel bolts holding it, the shield may be made of non-rusting material. Eventually it will crack or break. Replacing it would be tiresome because the bolts will be rusted in. If you ever do have to change this kind of part, apply copious amounts of copper grease to the new threads first. Even when the grease burns away due to the heat, there will be a fine copper powder remaining to lubricate the threads. Preferably use stainless bolts wgere they are liable to rust.
The reason it does not matter that the manifold is rusty, is that it is made of thick cast iron. The rust you can see is only a thin layer on the surface, the remaining thickness of cast iron is more than enough to do the job. Due to the great heat of the exhaust, ordinary rust-proofing plating or paint would burn off. If you want to make it pretty, you can buy special high-temperature treatments at great cost. By the look of the engine you are not overly concerned about prettiness. Some people have an unhealthy obsession with such things.

Most blatent ive got a supercharger pic ever!
I'd caution against using stainless bolts if there's any possibility of them coming into contact with ferrous metals. Stainless is electrolytically quite vicious and will accelerate rusting of the ferrous part it's in contact with. The worst situation is a stainless self-tapper into a thin mild steel panel.
