Since regular deep tuttle boxes can fail prematurely from the space left in the top of the box. With most of the force going upwards in the box, why don't guys selling foil boxes still make them with space still in the deep tuttle when the foil is mounted.
Are all deep tuttle foil heads slightly different from one manufacturer to the other. Is this why they can't make one size foil box without space fits all foil heads.
I know there are power plates if your foil has the 4-bolt conversion which mine does not so I saw

Seems to mount to the "power plate". But all these little bits to get your foil mounted properly can add up. Especially in my case owning a NP aluminum foil I would need to buy the deep tuttle adapter to mount the foil head then the power plate adapter to mount it to the board that$ 320 on top of the price of foils!
The tuttle boxes I buy come in 75mm and 100mm depth. You choose the size you want to match the thickness of your board. The box is installed and aligned at the bottom then shaved down to match the top and glassed. That gives you the ideal depth and the strength of being anchored to the top and bottom and all around.
Provided it is deep enough any deep tuttle head will fit into any deep tuttle box. You just need the right length screws.

Yes. Deep tuttle boxes are made to match the thickness of the board, not the fin head-hight wise. They seem perfectly good to handle the load of fins up to like 75cm for formula boards since there is no/little force going upwards in the box. But in foiling most of the force from the foil mast head is going upwards in your box hence the need for a power plate to spread the load and prevent the foil from moving upwards in the box saving it from damage... so I've heard. Some foils have a flang to help as well. Or you can make a wood spacer that sits in the gap in your deep tuttle box which is what I'm doing right now. Cheap option but time consuming and difficult to get it to fit right. I don't have a 3d printer so I'm doing it the old fashioned way.
The taper of the box does all the work. It wedges the mast in and stops it going in too far.
I think you need to talk to someone who knows about foil mounts and boxes and stuff. That thing about plates and upward forces sounds extremely dodgey to me.
I am guessing putting a spacer inside the box would not be a good idea. If the head needs to move then it probably should. I am imagining your spacer knocking the top out of your box. I have no technical knowledge. I just ride. But my experience is that the deep tuttle mount is beautiifully simple and robust.
I have deep tuttle foil boards with 100 and 250 hours on them respectively. They get jumped and surfed and all sorts of stuff. I ride them almost every day. They hold up just fine.
There are those in Windfoil that have already found out that Tuttle boxes can push out the top of boards if not reinforced.
what is also of interest is that a plate or such under the Tuttle head that spreads load onto board can reduce load on the Tuttle box by up to 70%.
