Question [Q] going from stock 4.4.3 to FactoryMod4.4.3


full picture: i rooted my nexus4 and installed Purity Rom (4.4.2) about a month ago. when the "[ROM] [4.4.3] [KTU84L] Pure Stock - Google Factory Image! + New Radio" was posted ( ) i wiped and installed (ROM and Radio and SuperSU) and tried it for a few days. it worked fine but then i saw that "[ROM][4.4.3][0506]FactoryMod: V3 ONLINE-White UI, RebootMenu, SystemMods, Adfree+More" was posted and I wanted to try it out ( ) so I wiped/factory reset and flashed the ROM and SuperSU but when i check the device info the build still shows at the Stock Rom. In fact i see none of the Mods at all. i tried wiping and flashing again and it still did not stick.

does this have something to do with flashing the stock 4.4.3 rom? is there something else I am not doing?
