Please note - primary head bolts must all have the same length. There is a Mid-Year split on the head bolts, if you have 2 different size head bolts this kit is NOT for YOU.
In every diesel car, there are high cylinder pressures that can damage head gaskets. Factory OEM head bolts are torque to yield, meaning you torque the bolt to a specific torque with a final 90-degree rotation that will place the bolt at its’ maximum stretch point.
