Depending on your engine management choice, your going to need some sensors. Now I believe, that some early ZX9R carbs came without a TPS and would require a custom bracket and a TPS sourcing. So its just easier to get a later model set, that includes a TPS (assuming you need one)

I don't know if your 1.8cvh is pre cat or not. If it is, then putting carbs on won't make any diff to the IVA.

thanks Deezee, my cvh is pre cat & the zx9r carbs do come with the TPS , i think the advice from Flyerncle & Bonzo is as usual spot on,
as my plan is to go zetec asap then theres no point in spending time & money setting up the cvh / bike carbs at this point, UNLESS if the bike carbs make the cvh more responsive & so more enjoyable to drive with a relatively low powered engine , as i know my cvh engine is in good fettle & have full service history on it etc etc then it may still be worth considering,
decisions decisions
