Aeroflow Performance head studs greatly improve your cylinder head-to-block sealing compatibilities. This is important in engines with high power adders such as turbochargers, superchargers or nitrous. They can even be a great addition to a mildly modified build as insurance against failure. All head studs provide a more accurate and consistent torque loading over traditional head bolts.
These head studs are manufactured from aircraft quality 8740 high tensile strength chromoly steel and cold-forged to ensure molecular integrity within the stud. Meaning these studs are rated up to 190,000 psi making them stronger than Grade 8 and OEM fasteners. All kits come complete with 12-point nuts and hardened washers for an even load distribution and accurate torque readings.
