Details:

As you increase the power output of your engine beyond its factory specifications, head and block may start to separate, causing bolts stretch fail. ARP recommends using the 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 inconsistencies in clamping force of fasteners when motor oil or other low quality lubricants are used. Then install the washers and nuts onto studs tighten them hand tight.

Its an ideal choice for individuals who want to push the limits of their B58 builds and require a stronger head stud. This ARP 2000 Head Stud Kit 203-4705 is designed for the turbocharged inline 6-cylinder B58 engines found in arias BMW chassis and Toyota GR Supra A90/A91. Screw studs into the block HAND TIGHT ONLY. Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.

Install the cylinder head and check for binding or misalignment. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Our Oversized Kit option utilizes Raps proprietary Custom Age 625 material combined with specialized insert washers for ultra-high boost applications. The Custom Age 625 option 203-4706 is made from Raps material that has a tensile strength of 260 ski, substantially higher than the 190 ski ARP 2000 head stud.

If the cylinder head studs protrude into a water jacket, lubricate block threads of with ARP THREAD SEALER. ARP Head Studs are stronger than factory bolts, ensuring your race engine stays together even under extreme conditions. This means allowing the engine to warm up its normal operating temperature, remain at temperature for several minutes ensure each component is uniformly heated, then turned off and cooled completely ambient. Look for obvious defects or shipping damages, plus proper fit, length and dimension.

Clean and inspect all hardware prior to installation. Chase if necessary with ARP Thread Chaser.
