Get your cylinder head back to peak condition with a complete, matched service kit. The Kibblewhite Cylinder Head Service Kit is designed to simplify a proper top-end overhaul by combining the key wear components you typically need in one package—valves, springs, retainers, guides, stem seals and a complete top-end gasket set.
When valves and guides wear, you can lose compression, power and reliability. This kit helps you refresh the valve train with proven components (including Black Diamond™ valves and titanium retainers) and replace critical sealing parts (Viton® valve stem seals and gaskets) so your engine can run cleaner and more consistently after service.
Key features:
✅ Includes complete top-end gasket kit (base gaskets, engine case gaskets, exhaust gaskets, head gaskets, plus required O-rings and washers)
✅ Full set of KPMI® standard intake & exhaust valves (Black Diamond™ forged stainless design for improved wear and reduced friction)
✅ High-performance spring kit with titanium retainers, CrSi valve springs and H.T. steel base washers
Benefits of use:
▹ Faster, easier cylinder-head service: the important parts are bundled and matched
▹ Restores sealing and valve-train performance for more consistent running and long-term durability
▹ Premium materials where they matter: titanium retainers, C630 bronze guides and Viton® stem seals
