Good To Know

Q: Should I replace both head gaskets at once? A: If both cylinders are being serviced, replacing both gaskets at the same time ensures consistent sealing and even compression across the engine.

Q: Do I need to check torque specs? A: Yes, always follow the manufacturer's torque sequence and values to ensure a proper seal and avoid warping the head.

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