Why this part
Steel valves are a known weak point once power climbs — they add mass, retain heat, and limit how hard you can rev. Manley's titanium construction addresses all three without compromise. For builds where the head is already open and the goal is reliability at the limit, cutting corners on valves is where engines get expensive.
