The N1EF is probably too lean on that clip position, and the clip will have been lifted to try and compensate for the overly rich small throttle response, which you probably won't be able to jet out with that needle.
The problems with the bolt on heads are that you still have a load of variables in terms of piston to head clearance (squish) and compression ratio, unless if you took the time to spec them up.
When your needles arrive you'll have something to work with.
I'd use the NEDW#3 with the jets you have. Make sure you drop the idle speed right down nice and low.
