Best way to create header for rollup door?
I've built a pole barn with a 12' X 10' rough opening for a rollup garage door. Problem is that unless I go to a much more expensive commercial door, the biggest door I can get is 10x10.
The rough opening is roughed in by 6x6s on both side and 2x8 top band at 12' what would be the best way to create a header at 10?
I was thing about using 2x6s on the sides against the 6x6s and then maybe a couple 2x8s sistered on top of the 2x6s somehow

Keep in mind that the roll up door will be perfectly square and hopefully level, once it's hung and sitting on a level cement pad. (the grade from right to left on the bottom of the door opening looks like it will present a problem.) But hopefully your 6x6's are perfectly plumb and parallel with each other. If not, you might want to shim the 2x6 trimmers so that at least they're plumb and parallel.
Maybe rip some 2 1/2" spacers to go between your 2x8's so that your header is like a box beam and is the same width as your 6x6's.

I agree with the grade problem. The landing of the door must be perfectly level. So you may have to do some grading to achieve that. In addition, I would pour a foot thick (or so) strip landing across the opening for the door to hit on to prevent it from digging into the dirt each time it is closed.
One observation as well, the bottom lateral board on the right side under the siding should have been pressure treated. You still have the chance on the other walls. Moisture will eat up that SPF board in short order.
