If R blocks K punt, and the ball rolls towards K's end zone, then muffed (barely touched by) K, the referee must determine if the original force to the ball (the block) would have been sufficient to move the ball into the end zone. If so, then it is a touchback. If the touching was a new force, then a recovery by K would be a safety or recovery by R would be a TD.

First, you don't quite have your own case right: if K muffs their own kick near the GL, then K put the ball into the EZ either way, by the kick or the muff. If the ball becomes dead in the EZ, then it's a safety.

But that's irrelevant to the OP: the ball wasn't muffed, it was blocked, and the kick put the ball into the EZ. And even if B had put the ball in the EZ, the ball did not become dead there, and the enforcement spot for the foul is still in the EZ.

For NFHS, you'd have the same foul, same penalty (except no LOD), and same options as NCAA (safety or possession to B where A recovered).
