I am Steve I own Stevens Kitchens . I am a certified FL residential contractor. We are removing a wall & found a load bearing header. The header & wall are holding up roof trusses. The existing opening is double 2 x 10 @ 64" wide, WE WANT TO OPEN IT TO 109" WIDE. I would like to pull out the header & wall & replace with double 2 x 12 header. Need sealed drawings for permit.
