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. This full engine set contains the bolts for
both cylinder heads, covering the complete engine in one order. 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.
