Adding an exterior door to my basement. I have a mason to cut thru the 8" concrete foundation and because the house is on a hill, the foundation where the door will be is only 20" below grade and slopes away from the house so I can excavate by hand.

The door will replace the existing 30" wide window and has no special header, but I need to go at least 40" wide depending upon what size door I install. I will build a temp support wall before cutting, but unsure about what type & size header I need. Thoughts? Do I need an engineer?

Yup.

Yes you do.

No one here can or should internet engineer your project for you.
