I had the same issue, mine were torque low by the dealer and let go, H11s and all.I was studded by H-11 curious to know why it blew n also why they are only torqued to 195 seems low, guy at the dealer doesn't want to put them back on cause of it.
I had a buddy lose some nuts from his batch of H11s. The ARP nut went right on.The H-11's have a lower torque spec because they are designed different. The thread pitch is different which requires a lower torque by you, but still puts a tighter clamp down.
275ft-lbs for an ARP will surely stretch the stud and make it useless. ARP has this posted right on their website specifically for 6.0 owners.
