Best size carb for a 402 at 5500' elevation?

I'm going to put a new Performer manifold and carb on Dad's 72 this weekend. Would the 600 or the 750 be the best choice? The engine is a semi-fresh (<1000 miles) all stock rebuild. It's just a driver, no hot rod. At this altitude, I'm torn between the 600 being too small and the 750 being too much.........
