The OEM head bolts typically can't handle the pressure from high-horsepower applications.\u003c\/p\u003e\u003cp\u003eConstructed using 8740 Chrome Moly with an added proprietary element ensures these studs are more durable and will not stretch like the factory bolts. The threads are rolled after heat-treating to deliver optimum fatigue strength.\u003c\/p\u003e\u003cp\u003eThese studs are rated at 225,000+ psi tensile strength and 205,000+ yield strength to keep your cylinder heads from lifting under higher combustion pressures. Assembly lubricant sold separately.\u003c\/p\u003e\u003cp\u003eA conventional bolt gets twisted as it is tightened, so it's reacting to two different forces at the same time. With a stud the force gets applied to the vertical axis, resulting in a more even clamping force which allows you to obtain a more accurate torque reading.\u003c\/p\u003e\u003cp\u003eThese studs are a must-have for high-horsepower applications and are reusable, unlike the OEM Torque-To-Yield (TTY) bolts which must be replaced after each use.\u003c\/p\u003e\u003cp\u003eAnother benefit of studs is they provide for easier engine assembly and proper alignment of the cylinder heads every time.
