R&D High Performance Racing Cylinder Head - 35cc (rec): Manufacturer part # 412-70035 - Stay ahead of the pack without running down your wallet with an R&D Racing head. These precision-cast heads provide superior design and function, raising your baseline compression ratio for greater overall power. Exact chamber volume match-up with CNC-machined combustion chambers. Increased top-end cooling and high-temp O-rings for sealing due to improved waterjacket areas. No more worrying about the failure of thin gaskets with these direct bolt-on heads. Choose your performance level; "Rec" heads raise the compression value to the optimum level for recreational applications, allowing you to use standard 92-octane pump gas while increasing throttle response and reliability. Higher-compression "Mod" heads are for highly modified engines using high-octane race fuel.. 412-70035 1 on hand
