What should the vaccum of an overhauled 1962 Starfire 394 engine be at idle

Somewhere between 18 and 22 inches of mercury.

The reason I ask is that I'm using the original brake booster and I've heard that it takes a lot of vacuum to operate.

I don't know where you heard that.
But the '62 Olds booster doesn't require any more vacuum than any other booster.
17 in. hg. .is usually considered sufficient.
