Mounting Thermoquad to air gap style intake. What adapter?

I have a 75 850 TQ (larger secondary) that I would like to mount on dual plane square bore intake for my small block 360. Going to be a learning experience including the TQ rebuild. This is strictly a street engine. Hood clearance may be a factor with the tall manifold. For those who have done this, what are you using???
I was thinking of the Mr Gasket 1932 and hog it out if necessary. I did shave down the plenum divider a bit on the intake.

I think you are on the right track. Smart of you to know there may be some modifying that may need to be done.
