Go to the All Things Root Guide sticky. KitKat ROM by bigsupersquid is listed there. Try the OS2SD version. You will get way more internal space. You will need Tech Vendetta's TWRP recovery and the Skinny Gapps. Go to tweaks, The Fly-On_Mod works great with KitKat to improve everything.

Hey sadielynn! I took the SlimRom (Jellybean 4.1.2) by thekraven (LG Optimus S developer) and modded it and gave it a Galaxy S4 theme, lockscreen, and keyboard. If your interested, check it out here : Bean_Whiz-CM10 Updated 10/14/2013 - Android Forums at AndroidCentral.com
You already know how to use Link2SD so try version 2.2.2CX first. All info needed is in first post.
