Check the taper in the bores and if not bad do what Mike Garblik said in post #3. The engine I've been flow testing carbs on for twenty years came out of a '61 Catalina more door I parted out. It had 80k miles on it and .003 or less taper in the bores so I did that rebuild on it but with an 068 cam and it has been a dependable little engine for almost nothing.
