These are the 11mm head studs and are a must have for anyone rebuilding their EJ engine. These are made from
8740 Chrome Moly alloy and better than any aircraft quality material. These have 1000% better fatigue resistance than your standard Subaru head studs. Allowing much higher performance compared to stock products. 

Modification to the block or cylinder head is not required, these will bolt straight into your engine. 

8740 Chrome Moly: Until the development of today’s modern alloys, chrome moly was popularly considered a high strength material. Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180,000 and 210,000 psi.
