Personally I make my own spacers.
I prefer a 4 hole or a divided spacer especially on a dual plane
or a divided manifold like an Offy 360

If you have a carb  boil problem you may be best
to pull the intake and weld up the heat stove cross over.
 
I got used to doing that when I was stationed at AAFB Guam back
in the 70's and never stopped, even on wintah cars. (intentional miss spellink).
 
There should be no need to re-jet.
If you use a big square opening on a dual plane manifold it may need a little richer jetting.
But I doubt it.
 
By the way, that is no illusion, I machiened the gaskets when I 5 axis ball
profiled the manifold. Makes for a perfect match.

Nope. I lost all my older stuff to a nasty divorce and a vindictive woman.
I prefer to machine out the hole for an aluminum plug and
weld it in, then dust it on a milling machine.
 
For an iron manifold i machine a rectangular hole with a seat about .1875 deep
and make a iron or steel plug go match
allowing the gasket to hold it in place.
 
I did an Offy manifold with no weld in the same manner as the iron manifold.
It worked so well that i was able to open up the heat stove and mill a slot on the throttle side
to make sort of a poor man's air gap.
 
 Note, the spacers in the above photo are at 3.5 degrees to level the carbs
as installed in the car. The studs are also rotated to 3.5 degrees as not to bind while the
attaching screws are perpindicular to the plenum cover.
