Won't recommend using the float valves from the K&L kits. They will change your float height due to a different height and spring tension. Also, I've heard of issues with main and idle jet sizes as well, though I personally haven't had any issues using the emulsion tubes, main and idle jets. Also, the needle jet taper is way off those aftermarket kits as well. Can cause weird fuel delivery at certain throttle openings. Stick with Honda for the needle nets, float needles and seats.
Also speaking of ignition these Densos will do you one better than the d8ea ngks.
