Default I need a new kernel!

Sup guys, currently I'm using the 7/9 build of Mahdi ROM. I noticed the kernel that comes with the ROM only has Interactive and Performance governors. My phone pretty much stays hot and my battery is awful. Any recommendations for an AOSP kernel for D800?
Phone: LG G2 D800
ROM: SlimKat
Kernel: Stock

Tablet: Nexus 7 2013 Stock

Deal with it.
