What size spacer best for heat soak slant 6 Carter

Ok. Couple questions. I can get a 1/2" no problem(have to check hood clearance), but I have a manifold mounted choke rod. How will raising the carb that much affect the choke? Also will it cause any issues with the throttle linkage? I know I will have to adjust the kick down. I don't think for that long of a rod it should be an issue. Mainly thinking of the choke. Will I need to make a spacer for that?

Also, 2 hole spacer? It's only a one barrel carb.
