Frequently Asked Questions

Q: Why choose steel valves over the original titanium?
A: Steel is significantly more durable and wear-resistant than titanium. While slightly heavier, this kit includes springs specifically designed to handle that mass, resulting in a setup that lasts much longer between rebuilds.

Q: Is the moly paste included in the kit necessary?
A: Yes. The included moly paste is critical for the break-in process. Applying it to your cam lobes and buckets prevents initial galling and ensures smooth operation from the very first start.

Expert Pro-Tip: Never reuse your old valve springs when installing new valves, especially when moving to steel valves. Always use the springs provided in this Wiseco kit. Furthermore, ensure you have your valve seats cut professionally to match the new valve profile; failing to seal the seat correctly will cause the new valves to burn out prematurely.
