The CHI raised inlet aluminium 23 degree head was designed for racers looking for more power without the added cost of building a new motor.
The CHI RI head uses the same components as a standard 23 degree head (pistons, rockers, inlet and exhaust manifolds). But because inlet ports have been raised .200″ much higher flow figures can be achieved. The RI Head also takes advantage of the higher flowing 40/60 valve spacing. Suitable on engines 330 – 430 cu inch. CHI heads can be supplied CNC ported in a number of port sizes to suit your application.
The price listed is for a pair of heads.$2,098.25–$5,001.14 Select options
