Glad to hear it! I think you'll like the Korky valve better than the Voreto (Type A) valve. Generally a quieter shutoff.
Also, for what it's worth, I have a little trick with the Korky if in the future you do want to lower it a notch. (Generally, the valve slides up about 1/8" in the grooves that lock it in place when you twist it, which may account in part for why it's higher than you wanted.)
If you want to lower it without removing it, my little trick is as follows: Turn off the water and flush the toilet. Put a bucket underneath where the water will come out of the hole for the fill valve. Remove the lid from the toilet. Holding the shank of the valve from underneath so the valve doesn't turn, loosen the mounting nut that holds the fill valve underneath the toilet just a bit. Now, holding the top of the fill valve in place with your right hand, twist the shank of the valve from underneath to unlock it with your left hand. Slide it down a notch or two with your right hand, then twist the shank back to lock, again from underneath. A little water will drip over your hand while you do. Then tighten the mounting nut again by hand while holding the shank. Done. You don't even have to unscrew the water supply hose.
