I have a miller head with the NICR marking. It has a miller carburetor and intake manifold. The rocker box has Miller Hi Speed head Los Angeles This head designed for Anti Knock Fuel and High Compression Plugs. The updraft intake is aluminum and the Miller Carburetor has a 4 or 5 jet system and a rotating venturi. Does anyone else have such a carb, or information on adjusting it? I also picked up a plain rocker box cover on EBay some years ago.
