Dennis Kirk Part #: 147903
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

Kuryakyn Wild Things Domed Pistons for 95 in. Twin Cam Stock Heads - Forged 10.5:1 (3.875 in. bore): Manufacturer part # 445 - They are forged from the highest-grade aluminum alloy designed for piston use making them the strongest piston on the market for your 95 in. Twin Cam. The special skirt shape and material means less break-in time, quieter running and a stronger resistance to scoring. The lightweight design results in less power robbed by the forces of inertia and less vibration. Larger and deeper valve pockets will handle larger valves and cams without extra machine work. The decks are slightly raised for a tight squish with stock .045'' thick head gaskets. This is extremely important and results in better combustion efficiency and power. The redesigned dome shape on the high-Compression piston for stock heads results in less pumping losses and better combustion efficiency and detonation controls. Kit includes pistons, rings, circlips and wrist pins.. 445
