Were is the highest point of vacume on a carborated engine? Just below the throttle plates, Or is vacume equal throughout the intake system. I have noticed power brake booster usually attached to port in carb under throtle plates. I wasn't sure if this made a difference or was just a point of convience for the auto manufactures.

And yeah I can't spell for S#@%.
I'm no expert, but I think the highest amount of vacuum is at the intake manifold. Most Fords, at least the ones I have had, have both the trans and power brakes vacuum source on the rear of the intake manifold itself. An Edelbrock intake that I have on my 302 also has the power brake/trans vacuum source on the back of the intake.

I just got a new Edelbrock carb, and it says to connect the power brakes at a fitting at the back of the carb so I assume this is full vacuum. I have neither power brakes nor an auto trans on this particular car so its not a situation for me.
