Default LS980 KK baseband ?

Is there a difference between these KK baseband ? KK_Baseband_LS980.zip http://www.androidfilehost.com/?fid=23329332407584588 and the ZVC bb (LS980ZVC M8974A-AAAANAZM-2.0.20046 by QUALCOMM, Incorporated Mar 09 2014) in autoprime's thread http://forum.xda-developers.com/show....php?t=2451426 ? The file size is different.

I wanna flash it for a custom D802 KK ROM over LS980 device . TIA
