You will pretty much need to stick with a stock manifold. That carb has heat passages that come up from the manifold. Do you want to use that carb for originality reasons? A Q-jet on an aluminum manifold would work better & be close to original.

The 4GC carburetor was used in the late '50s up through the '66 model year. It was used on 220 HP 283 "Power Pack" engines, 250 HP 327 engines in passenger cars and on the '66 327 truck engines.
You need to find an intake from a '60s era engine. Here are some casting numbers for manifolds used in the '62-'66 time frame: 3844457, 3866922, and 3882858. These manifolds are fairly common and not too hard to find.
Hope this helps.
