Load bearing wall removed -- WITHOUT HEADER

Greetings All

An 7 foot interior load bearing wall has been removed creating an 10'2" opening (including 2x4 jack studs)

Although my friend assured me that the wall was not load bearing -- at the time I didn't know how to determine a load bearing wall, however after doing some research on the internet and picking up an home depot 1-2-3 book, I'm now sure it is load bearing (the wall is perpendicular, center and beneath overlapping joists, and has a double top plate)

The remaining 2 ft long cripple studs extend from the double top plates at the joists, screwed to a 2x4 which sets on a 2x4 7ft jack stud.

this so-called 2x4 header does even span the full 10ft opening its only 7ft and it is screwed to the 3ft door header which was left intact.

Based on my limited reseach I intend to cut the cripple studs shorter to allow for the placement of a 10'2" long header that will be made up of (2) 2x8s with 1/2in plywood resting on single 90in 2x4's on either end of the opening

How do I tie the header to the king stud?

How do I attach the header to the jack stud?

Will my little plan work? Dose the wall need more support than what I plan?

I had already cut the 2x8's for the header and 2x4's for the jack studs, but I thought I will seek a little more help before continuing.

I have limited funds at the moment so I haven't contacted a contractor.

This is my first post, I searched previous posts but couldn't find answer.

It has been a month since this was done, yet the attic has not caved in.

Sincerely
Hanging by a 2x4

 

Take a look at the info on this page, I think it will answer most of your questions. Just an attic above this right?
