The M30B30, M30B34, and M30B35 is a 6-cylinder engine that was used in a variety of BMW models, including the E3, E9, E12 and E23.

Installing ARP head studs 201-4602 on a BMW M30 engine can 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.

Please note: After initial assembly, it is necessary to allow the engine to complete a full heat cycle, then re-torque your head studs to spec. This means allowing the engine to warm up to its normal operating temperature, remain at operating temperature for several minutes to ensure each component is uniformly heated, then turned off and cooled completely to ambient temperature.

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.
