Basically, your kernel is the exact same as the one from the other package (well, block 12 is). Block 11 is the normal kernel, and the only difference between it and block 12 is emboldened above. Block 12 is labeled as the Recovery kernel, although the bootloader does not use it for recovery; it passes an extra parameter to the normal kernel (which is why custom kernels can get stuck in recovery on this device). In fact, it never uses block 12. Nobody outside Samsung may ever know why...

P.S. you may want to rename the thread...

The ROM may have been modified, but the kernel/recovery is 100% the same as Shogunmark's and therefore 100% stock.
