Default SGH-T759

Hello guys i finally was able to install a custom ROM in my exhibit 4G SGH-T759 and im happy with it
I found a kernel update for ROMS who use kernel and mine uses that so i was thinking can i try this kernel out without hardbricking my phone , if it get's softbrick it is not a problem since i know how to flash the stock rom but for a hardbrick i can't do anything
On the forum where ive found the kernel update the post says that "This kernel will probably only work with roms based on kernel" so it should work with mine right ??
And sorry i know that this forum is for the newest galaxy exhibition 4G but i was not able to find a forum for the old version
