Did They Make Square Bore AVS Carbs Made That Only Had The Small Bolt Pattern On The Base Plate?

Making a spacer is a LOT of work to mount carb that can easily be drilled to work with your intake......... & it will not harm or weaken the carbs.
I have TWO engines that have 4500 Holley bolt pattern intakes......& they TQs bolted directly to them without a spacer.
