This is what I mean, the old one was the one I pulled off, it has a metal plate in the middle with a hole and the new one has nothing, what do I do?

That is for the exhaust cross over that heats the intake system for cold weather operation. I believe this is in a boat so I don't imagine you need/want the exhaust to be heating the intake so just let the new gaskets close of that cross over. The only exception would be if you have a mechanical choke that requires the heat in the intake to open the choke.

No there isn't even a choke on the carb, so I should just run the gasket like that and plug the holes

Is there a hole in the intake manifold? If not, you don't need it it, run gaskets as they are.

if you need a cross over,then cut a hole.
Most high performance people block the hole

Get a ball peen hammer or other metal tool that has a rounded end on it. Lay the intake manifold on the bench upside down. Lay one of the gaskets on the intake and drop 2 or 3 bolts through the bolt holes to locate the gasket on the manifold. Lightly tap the gasket at the edges of the heat passage hole. Many light little taps will score the gasket perfectly for you to cut the piece out with a sharp knife and make a passage for hot air. Do the other gasket the same way.
