Have to install (2) new 400A breakers in this board. They have a note to remove one of the switches to make space for new switches.
Seems like there would have to be modifications done to board to so this.
This couldn't be a simple remove and install?

When installing new( not a draw out) breaker into an existing board is it a lot of work?

It’s more than just mounting into a distribution panel. What Bob means is that there are usually several hardware aspects that you have to deal with in that there are depth issues and distance to the main bus to contend with, new doors etc.. If the switchboard mfr is still in business you can usually get the hardware kits to do that, if they are not, you may have to go to an aftermarket company to get them made.
 
Depends on the manufacturer, with ILine, it’s a simple pull out-push in. The existing breaker being removed to free up enough space on the buss. Other manufacturers, you have to get another “finger” kit for the higher amp breakers. Without knowing the manufacturer and style, your shooting in the dark. You may also need filler plates.

Yes, Square D I-Line is kind of the exception, although I would argue that it’s a panelboard, not a switchboard. There is a slight difference. The OP just said “board” though, so I may have misinterpreted.
