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.
