Yes and yes. The stock power valve circuit will feed too much fuel, it needs to be restricted down to like .020" holes each side.
FYI, old American Motors 2 bbl. carb adapters that used to be part of every 2 bbl. manifold make good adapters, the smaller inside hole pattern fits the small pattern on the 2.0 manifold.
Sure you got a 2.0? '74 came with 2.3........... .....
