Embed plate in concrete with headed studs
(OP)
Whats the best way to design a embed plate at a corner of a piece of concrete that has the headed stud coming off the interior of an angle at 45deg into the concrete. A contractor I work with alot likes this detail, I am just not 100% sure what design value to give it. Do you take the edge distance from the end of the stud, or some average value?

What forces are being transmitted to the angle? Can you re-pose the sketch with some force vectors? I am guessing horizontal if that is a top of a wall panel?

Headed stud design per StructSU. If there is room in the panel you could go with a vertical stud and place a continuous #4 on the left side of the stud for supplemental reinforcement when the panel reaction is to the left. When the shear is to the right it will simply compress the angle so no worries there. If the headed studs are giving you issues then you can always use a channel with legs down or a bent plate saddle (shaped like an upside down "U") that will give you full shear value of the concrete without needing the studs.

The more I think about it, the more I like an inverted channel or bent PL saddle to cap the wall. Then you get the full shear of the concrete, and your vertical bars in the panel will also extend through that theoretical shear plane.
