Custom Rom and Phone Compatibility?

[sventisep]

I want to install some custom rom on my phone but I'm uncertain about a few things.
I see on this link:
http://android.appstorm.net/how-to/rooting-and-roms/how-to-find-custom-roms-for-your-android-phone/

That there are OEM Custom roms and AOSP roms.. I want to use AOSP.

My question is, if a particular custom rom is AOSP and it is based on the operating system of my current phone (Android KitKat 4.4.2) then will the custom rom work on my phone?

Has anyone had any experience with this?
Thanks

ROMs are specifically made for the device they're being installed on so if you're downloading from a reputable source (xda, here etc), the base requirements for the ROM, what it's compatible with and any prerequisites will be in the Opening Post of the thread it's in.
