PRELOAD TORQUE RECOMMENDATIONS 7. Install the cylinder head and check for binding or misalignment. When installing ARP head studs on an engine, its important to follow the manufacturers instructions carefully and use proper torque specifications sequence. Installing ARP head studs 201-4602 on a BMW M30 engine can provide several benefits, including increased clamping force and improved gasket sealing, which help prevent failure.
Screw studs into the block HAND TIGHT ONLY. Look for obvious defects or shipping damages, plus proper fit, length and dimension. Then install the washers and nuts onto studs tighten them hand tight. Clean and inspect all hardware prior to installation.
To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. 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. Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. 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.
Its also a good idea to have the cylinder head and block checked for flatness resurfaced if necessary, ensure proper seal. Installation Instructions: ARP recommends using the ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to motor oil. If the cylinder head studs protrude into a water jacket, lubricate block threads of with ARP THREAD SEALER.
