Greatly improved clamping reduces the risk of head gasket failure. Recommended 45, 70, 85 ft/lbs using moly lube. Studs last for the lifetime of your engine making them a great investment over the single-use torque to yield bolts from the factory. 

Teflon tape required for threads going into the block to prevent coolant leaks. Do not use a paste to seal these.

Installation Method for Head Stud Kits 

200,000 PSI 7/16 inch Diameter

  1. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if necessary with ARP Thread Chaser. 
  2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit, length and dimension. 
  3. If the cylinder head studs protrude into a water jacket, lubricate the block threads of the studs with ARP THREAD SEALER. 
  4. Screw studs into the block "HAND TIGHT ONLY". NOTE: Loctite may be used if a permanent mounting of the studs is preferred. The fasteners, however, must be torqued prior to the Loctite setting up. 
  5. Install the cylinder head(s) and check for binding or misalignment. 
  6. Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. 
  7. Then install the washers and the nuts onto the studs and tighten them hand tight. ARP recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to motor oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when motor oil or other low quality lubricants are used. 
  8. PRELOAD (TORQUE) RECOMMENDATIONS: following the manufacturers recommended torque sequence tighten the nuts in three equal steps to 80 ft lbs with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.

High quality, very well constructed. They're perfect for my 590 hp grand prix. I purchase all my performance parts from zzp. Great company.


Get ready to grind away.

If you install these be sure you are ready to grind the manifold/headers. I have Pacesetter headers and the rear cleared (I think) by the thickness of a sheet of paper. The front aren’t even close! I have to grind 3 different spots. Wish I would have stuck to tty bolts. On a side note the studs and nuts are heavy duty!

Arp head studs

I received my package last Thursday and went to install my arp head studs. Well after getting one head installed and prepping the 2nd to be installed I noticed they sent me 10 long studs and 6 short. Ive been patiently waiting to get my issue resolved so my car can see the road again. But after emailing them , all they asked for was pictures of what I received. Which is kind of hard when my car is half put back together. I sent them a photo of the 2 long studs I am unable to use. Still waiting for something to happen to get this resolved. Very disappointed. Usually my experience with zzp is a lot better than this. But as for the studs them selves they look great.

Quality but lack of due diligence

Parts arrived as expected, quality was all there from arp, but i wish ZZP and put in the item description that, with these studs you also have to do quite a bit of modification to the rear exhaust manifold to get all the manifold bolts/studs in. ones between the valves fit perfect.
