4150/4500 adaptor

Hey guys. I am building a low deck 499. It'll have TF 270's on it, so max wedge ports. I have an Indy 4150 max wedge port intake I'm going to be using, but i have a 4500 dommy carb. I know there is an adaptor to make it work, but does it really choke down the flow? Is there something i can do to the adaptor/intake to improve flow? Which adaptor has anyone used that works well? also, Just curious if anyone has had a side by side comparison to a 4500 intake to a 4150 intake. Thanks guys!
