I raised my door tracks that has torsion springs until the cable drums were 1/2 inch below the ceiling.
I raised the tracks on the wall 4 inches and added 4 inch extensions to the bottom of the tracks.
I made longer lift cables so that there would same amount of wraps on the drums as it originally had when the door is closed.
Doing that allows the open door to be above the bottom of the 2x12 header.
