Clone Modified Cylinder Head - This is for the serious racer who demands nothing but the best. These cylinder heads are expertly hand ported to match flow and velocity optimizing performance. From the ProFlow Manley chrome plated stainless steel valves, fatigue resistant valve springs, hard anodized retainers and split keepers there is nothing left to chance. We also have an optional intake/carb kit that includes a Tillotson HL388 series carb that is built and tuned specifically for OHV 4 cycle engines. The manifold will be matched and ported to that specific head. Chose your option of a .790" or .880" venturi and your choice of fuel gas or alcohol. The intake kits comes with the carb, filter adaptor, linkage and manifold. See the K & N section for an air filter (RU-1700) and pre filter (RU-0500PK) to complete the set up. The 24/27.3mm valve set up is recommended for the stock appearing classes using a bored out stock carb and the 25/30mm valve set up is for the larger carbs.
