Looking to update carb of assorted parts.

Bought a 94 FLHTCU with stock motor. Currently believe it has a dynajet needle. Have loriginal Keihen 42 pilot, Keihen 70 accel but the main has no Keihen stamp. Size 180. Emulsion tube had two holes on the side. I want to replace main with same size but add CVP tube because I believe the threads are different on the current tube (possible dyna). One question is should I jet the same 180 with the CVP emulsion tube with more holes. I will also be replacing the needle and needle jet just to make sure they all match. Vacuum slide is worn so will be replacing too. Likely add idle and mixture screws (already drilled). Considering V-ductor.

So I had posted this in the wrong place some times ago. I now have a tuner kit to replace main with same size but now more standard threads using premium tuner kit. Also new slide as mine was worn near the base. renewal kit for float valve and gasket and accelerator pump diaphragm. Replacing needle jet with CVP needle jet (matching manufacturer).
Also adding V-ductor.
You would think I would have ordered a new inlet elbow. Well that was ordered as a second order. I don’t have any problems with the plastic elbow now.

Opinions on replacing the elbow just because?
