Specs At A Glance

Good To Know

Q: Can I reuse the old gaskets if they still look intact? A: No, gaskets compress and harden with heat cycles, so they should always be replaced once the top end is opened. Reusing them risks compression loss and water leaks.

Q: Does this set include the base gasket and head gasket? A: Yes, the set is built around the head and cylinder base seals, along with the exhaust and smaller O-ring seals needed for the job. Confirm your exact engine configuration before ordering.

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