    What's the difference between these and the 12 point

    What horsepower are these good for compared to the arp 2000 head studs? in the process of building a motor for a 300 shot and dont want the heads lifting or issues with fasteners. thanks

    • This ARP Head Stud Kit is closer to factory and would not be recommended for that kind of build anticipating higher power numbers or taking that big of a nitrous shot. ARP would recommend their part number: 256-4001.

      Easy install!

      Be sure to get a long tap to clean threads. Also, assembly lube comes in the box even tho it isn't listed.

      It's ARP what's not to like

      picked up these arp head studs for my boost build, fast shipping like always thanks am you rock, quality is not cheap or junk at all. I recommend using the moly lube when torquing down the heads.

      ARP only way to go

      ARP Headstuds are the only way to go if for any reason you have to tear apart your engine or heads. Especially if your pushing more than 500 horses. Factory ford bolts are one hit wonders, but you can reuse the arp studs over again.

      Best on the market

      Definitely the best head bolts money can buy. Re-usable and very sturdy build. I would recommend them to anybody that has a pony that puts power to the ground
