If I were to get into a diy build on a 12x20 with say a 355mm g-claron, what length of bellows would I need for such a large format If I wanted shoulder/headshots? Just tinkering with some ideas but im a little lost on how to figure out the length needed for something so far past infinity.

Find out the bellows draw required for the focal lenght at distance.
Should be over half a meter for headshots!
