Exactly the point.
Unless you have an aggressive (not race) cam and heads that flow 280-300+ CFM just stay as you are.
A. It works and is not problematic.
B. You have no demand from the other systems in the motor for more carburetion.
C. It's the least expensive thing to do.
Take the advice from Holley man with a boulder of salt.
Progressive linkage alone will not lean certain cylinders. That's more a function of which intake you use.
Larger than 390's are NOT too much for your combination. Vacuum simply allows the engine to only use the CFM it wants, making larger carbs a bling thing.
You're fixated on progressive-or-not linkage.
A. Leave it as is.
B. Experiment and vary the rear carb feed-in in small stages.
C. Experiment and make a 1:1 link and see how it runs. I did, it does.
