The Performer RPM retains the stock rocker arm, intake/exhaust ports and spark plug location for use with factory components. Like all the other cylinder head, this has been designed, tested and cast from 356 aluminum and heat treated to T-6 specs in our facilities in Southern California to guarantee you get the best from a name you can trust. - Combustion chamber volume: 58cc - Intake runner volume: 305cc - Exhaust runner volume: 115cc - Intake valve diameter: 2.165" - Exhaust valve diameter: 1.600"
