Why Choose This Rebuilt Cylinder Head Assembly?

• Genuine OEM Honda Casting Never settle for cheap, low-grade aftermarket aluminum castings that warp under heat. Built around a genuine Honda core, this head guarantees exact factory fitment, superior heat dissipation, and the legendary structural integrity you expect from Honda engineering.

• Precision Japanese Engineering: Shindy Valves Outfitted with brand-new Shindy Intake and Exhaust Valves (Made in Japan). Engineered to meet or exceed OEM specifications, Shindy valves deliver exceptional heat resistance, reduced stem wear, and long-lasting sealing power—preventing premature valve float and compression loss.

• Professionally Reconditioned & Machined No guesswork or tedious valve lapping required. Every head undergoes a complete overhaul by experienced engine builders:

  • Ultrasonic Cleaning & Inspection: Stripped, thoroughly degreased, and checked for cracks or material fatigue.

  • Precision Valve Job: Valve seats are recut/lapped to ensure an airtight seal.

  • Deck Resurfacing: Mating surfaces are checked and flat-surfaced for flawless head gasket sealing.

  • Fresh Valve Stem Seals: Pre-installed to stop oil leaks and keep combustion clean.

• 100% Plug-and-Play Convenience Skip the hassle of sourcing individual springs, retainers, valves, and seals. This unit comes fully assembled—just torque it down to spec, set your valve clearance, and hit the starter.
