Oh, I'm not proposing that extreme be applied. I'm somewhat fishing here for anyone who knows what RUF and other tuners applied when they ported these engines. The idea being to use street, non-racing heads.
The stock 3.2L N.A. motor has the same size valves but 8MM larger intake and 4MM larger exhaust ports.
