The listing is for a Brand New high compression racing cylinder head for the Suzuki A50, AC50, AS50, AP50, RV50, TS50, MT50, F50 etc. These kit parts are extremely rare and impossible to obtain. I manufactured (CNC billet) a small number of cylinder heads for my racing Suzuki A50/AP50 engine based on the original Suzuki racing head with the improved performance from the a central spark plug and better material (AA7075). This head will increase the compression ratio and performance of your engine.Chamber volume is 5.5cc, 41mm piston. Longer and thicker cooling fins for extra strength and better cooling. NGK BR8EVX spark plug is recommended to be used with this head. Comes complete with 4 Deep nuts and washers. I have couple of these cylinder heads for people that run a big bore kit.
