I just thought people would like to see what goes into porting a Rb Head,
The Rb25/26 heads really struggle to make power on the standard ports,
This is for a customer in Greece, its going to be running a V-cam system, with standard valves, the head is good for around a 1000bhp on standard valves with the port sizing/spec.. (obviously depending on turbo specs and cams etc)
