If the jat khaps really want to avoid marrying cousins, they really should look from brides and grooms from African negros, since the split is 85000 years ago.
Every Ashkenazi jew is related at the level of 4th cousin
One of the interesting facts of evolution is that at each branch there is a bottle-neck effect, and fairly high levels of inbreeding, thereby concentrating the genes.
I have seen 2-3 cases of genetic defects even at the level of 2nd cousin, but at this genetic distance, it is not clear whether they are purely random events.
At the level of 3rd cousin and 4th cousin, the genes actually start favoring in-breeding, due to genetic compatibility
