Enginetech TTY (Torque-to-Yield) head bolt sets are engineered to OEM specifications for proper cylinder head clamping force during engine rebuilds. TTY bolts are designed for single use - they stretch plastically during torquing to achieve precise clamp load and must never be reused. Enginetech packages head bolts in per-head quantities for popular applications, making it straightforward to order exactly what your engine requires. Always follow the manufacturer's torque sequence and torque angle specification when installing TTY head bolts. Verify part fitment by year, make, model, and engine displacement before ordering.

WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.
