Frequently Asked Questions

Q: Are these steel valves a direct replacement for my stock titanium valves?
A: Yes, these are designed as an engineered replacement. However, because steel valves are heavier than titanium, you must use the specific springs included in this kit to maintain correct valvetrain stability.

Q: Do I need to perform a valve job when installing these?
A: Yes, whenever you replace valves, you must have the valve seats cut or lapped by a professional machine shop to ensure a proper airtight seal.

Expert Pro-Tip: When installing new valves, don't just rely on the seat seal test. Check your valve stem-to-guide clearance precisely. Even the best valves will fail prematurely if the guides are worn out, as they will wobble and hammer the seat faces. Always check your clearances against the service manual before finalizing the build.
