Re: arp head studs
The arp bolts have a much higher tensile strength than the stock bolts. The reason people upgrade to arp is because the stock bolts will stretch under boost, especially on a SOHC if you are running too much timing. It will cause leakage into your coolant passages under boost, which will pressurize the system and force coolant out into the reservoir and cause severe overheating... It is called head lift.
