Introducing our amazing Iconic Spec PRB K20 CNC ported cylinder head. After testing and with years of experience we have a high flow cylinder head which works amazingly on both the K20 engine and K24 engine. During the porting process our design does not make the intake port massive but instead concentrates on making it flow fast while creating much needed turbulence to aid air and fuel mixture while entering the engine. On the outlet side the port has been enlarged to aid fast exhaust gases release and this side is smoothed to suit. We install Ferrea bronze valve guides into all Iconic CNC ported cylinder heads which means your valves will be as stable as possible during high reving fun. To finish the cylinder head all valve seats are cut with a thin race seating for your valve. Finally the cylinder head is resurfaced to allow for a perfect head gasket seal. This head will make excellent power gains on any high performance K20 or K24 engine.
