273 4 barrel manifold questions

Another question. Would aftermarket intake be better, because it would open up carb choices? Kind of like the idea of period piece, as I have a set of cal custom valve covers(with the box listing applications up to 1973), not too worried about originality, cause I can always go back to the 2 barrel. Gives me some ideas to look out for. For me half of the thrill is in the hunt.
thanks guys
