other blow through 2 barrels

Holley 2300 is really hard to get a hold of I'm tempted to run a 4 barrel. I would be using an adapter for my 2 barrel intake and I'm plannin to wire the secondaries shut. I'm wonfering if this will cause any issues. I seem to recall some one on the. Org maybe that said it caused problems for them. Anyone have any experience with this?
