The ultimate race head!! You will not find a better flowing 22R cylinder head than LC Engineering's Stage 5 head. The head has not just been ported; it has been re-designed! The stock Toyota swirl-port intake has been opened up to flow over 240CFM! What goes in must come out, so the exhaust port was expanded to flow over 160 CFM to better match the flow of the intake. The head is fitted for huge 48mm intake and 40mm exhaust valves. These are the biggest stainless steel, swirl polished valves we can fit in the chamber. This race-proven design has been seen throughout the winner's circle in many forms of racing.

NOTE: This head is designed for naturally aspirated high compression engines. If you are not running at least 11:1 Compression Ratio, we will not build the head. We would recommend our Stage 3 Cylinder Head for lower than 11:1 compression applications. LC Engineering will not warranty any cam damage if you do not purchase new Toyota rocker arms from LC Engineering, or a complete rocker arm assembly from LC Engineering at the same time as purchasing this head.
