Takegawa F5 F7 Cylinder Head was sent to us from Belgium in a very bad shape. A valve dropped, and as a result, seats, guides and combustion chamber were destroyed..

All it took was some AaSa magic, and the result is better than new! Combustion chamber was tig welded, copper alloy seats and guides were installed, stainless steel valves were custom made, and while at it, precision CNC porting was implemented to boost performance and value for a rare cylinder head!
