Thermoquad or Holley?

Im disappointed about my intake, my buddy told me he had a 71 casting and after I went to get it, its a 73 with the electric assist choke, I'm hoping it will still flow as well. Recon I need to keep looking for a 71?

No EGR you are good to go. Get the truck choke, without the heater, or use as is. Flow is pretty much the same.
