ARP 204-4210 Porsche 911 996 997 Mezger 3.6L GT2/GT3/Turbo Head Stud Kit

ARP Pro Series cylinder head studs are cold-forged to ensure molecular integrity. They're heat-treated prior to thread rolling and machining. ARP Pro Series kits are also available with 12-point nuts, and all studs come complete with hardened parallel washers for an even load distribution and accurate torque readings.

Special order item - please call for availability and lead time before placing your order.

Installation Method for Porsche Head Stud Kit


Part Number: 204-4210

Application: Porsche 3.6L Turbo Water-Cooled Engine



  1. Always verify the part number for your application with the part number on the side of the box and the part number on the instruction sheet.

  2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages plus proper fit, length, and dimension.

  3. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if necessary with ARP Thread Chaser part number 912-0003 (M10 X 1.5).

  4. Screw the head studs into the left-hand and right-hand engine cases "HAND TIGHT ONLY". NOTE: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERRED.

  5. Install the cylinders and the cylinder heads as described in the Porsche factory service manual. Check for binding or misalignment.

  6. Lubricate the stud threads, nuts, and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. 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.

  7. Following the manufacturer's recommended torque sequence, tighten the nuts in two equal steps to 38 ft-lbs with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Note: ARP Ultra-Torque Fastener Assembly Lubricant has been specifically designed to reduce tension preload scatter and eliminate the need to cycle high-performance engine fasteners before final installation. ARP Ultra-Torque far surpasses all requirements offered by previous ARP lubricants in terms of fastener preload repeatability and performance lubricating properties.
