Anyone know where to get ARP 625+ headstuds? haven't called ARP directly yet to get a part number and since there's absolutely no one other than a small handful of guys wanting to make big numbers on the 7.3 no one bothers to advertise.
I don't think arp makes the custom age 625 studs for the 7.3. I'm going with extreme studs on my current 7.3 build. They are big in the cummins and tractor pulling world and they use h13 material.
