Good To Know

Q: Can this gasket be reused if the engine is taken apart again? A: Cylinder head gaskets are single-use and should be replaced whenever the head is removed. Reusing one risks leaks and poor sealing.

Q: Should head bolts be replaced at the same time? A: Many LS head bolts are torque-to-yield and are not meant to be reused. Check your service information and replace them as specified.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
