The standard M12 head bolts are a stretch bolt reducing the clamping force on the gasket which can lead to head gasket problems over time.Obtaining the optimum cylinder head-to-block sealing is especially critical in turbocharged engines.
That's why ARP® head studs are popular among leading Sport Compact/Import racers.ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 200,000 psi.
