This cylinder head also significantly improved the performance of the engine by using a more modern crossflow cylinder head design, compared to the original which used a reverse flow design. A normally aspirated version of this engine produced 230hp. Shortly afterwards, OS Giken also released a 24 valve version of the same cylinder head for the 6-cylinder version of the L-series engine, which produced 320hp normally aspirated, with a rev limit of 9,000 rpm. In 2013, a redesigned version of the 24 valve DOHC cylinder head was released. Osamu Okazaki says that he redesigned every component with more modern technology and materials. The rev limit of the newer model is 10,000 rpm, and a normally aspirated version of the engine produces 420hp.
