Performance Head Gasket & Head Stud Kit for BMW M30

This kit includes a high-performance head gasket and head stud kit designed for BMW M30B30, M30B34, and M30B35 engines, replacing BMW part numbers 11121730226 and 11121730227. Compatible with BMW E3, E9, E12, and E23, this setup ensures maximum sealing for high-performance applications.

MLS Head Gasket (Cometic)

Ideal for high-output and forced induction builds, the Multi-Layer Steel (MLS) head gasket offers superior sealing without the need for additional sealants.

Key Features:

  • Multi-layer stainless steel construction for strength and corrosion resistance
  • Resists shearing forces and minimizes bore distortion
  • Withstands extreme heat and pressure
  • Not compatible with engines using O-rings or receiver grooves

Cut Ring Head Gasket (Athena)

For extreme boost applications (16+ psi), the Athena Cut Ring Head Gasket provides unmatched sealing.

Key Features:

  • Reinforced M0115 material, OE-approved for durability
  • AISI 304 stainless steel Cooper Rings bite into the aluminum head for a stronger seal
  • Recommended for turbo and nitrous applications exceeding 2 bar boost

Installation Notes:

  • Cylinder head and block must be cleaned and resurfaced for proper sealing
  • Follow manufacturer torque specs for installation

Please be aware that the gasket  should have a size that is 0.5mm to 1mm larger than the piston. For example, if the piston measures 84mm, then the gasket should be the next size up, either 84.5mm or 85mm.

Head Gasket Installation Instructions:

  1. Make sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant.

  2. Install the head gasket on the engine block and ensure that it is properly aligned. Avoid twisting or bending the gasket during installation.

  3. Place the cylinder head on top of the gasket and install the head bolts or studs in their correct positions.

  4. Follow the manufacturer's recommended torque specifications and tighten the bolts or studs in the proper sequence to ensure even clamping force across the gasket.

  5. After the initial tightening, re-torque the head bolts or studs after the engine has been started and then allowed to cool to room temperature. This will ensure that the gasket is properly seated and compressed.

  6. It is NOT recommended to use any additional sealant on the gasket. Using additional sealant can hinder the performance of the gasket.

Head Stud Kit

Installing ARP2000 head studs 201-4602 on a BMW M30 engine provide several benefits, including increased clamping force and improved head gasket sealing, which can help prevent head gasket failure. This is particularly important on high-performance or turbocharged engines, where the increased cylinder pressure can put additional stress on the head gasket and bolts.

When installing ARP head studs on an engine, it's important to follow the manufacturer's instructions carefully and use the proper torque specifications and sequence. It's also a good idea to have the cylinder head and block checked for flatness and resurfaced if necessary, to ensure a proper seal.

Installation Instructions: 

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”.
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.
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.

PRELOAD (TORQUE) RECOMMENDATIONS

7. Following the manufacturers recommended torque sequence tighten the nuts steps 1-3


Step 1: Tighten to 30 ft-lbs.
Step 2: Tighten to 60 ft-lbs.
Step 3: Tighten to 90 ft-lbs.
