Hello everyone. I would appreciate some advice from the community. I acquired a 2013 250 xcf-w that had been partially disassembled by the original owner. (Long story). I am looking to rebuild the top end of the engine and I need a complete cylinder head with cams, valves, bearing bridge etc. I have had no success locating a used head and I cannot afford to buy all the parts individually. I have looked at part numbers for hours and I realize that the only direct replacements would be from a 2012 250 xcf-w, a 2013 250 xcf-w, (obviously), or a 2013 250 exc-f. Does anyone here know where a person might track down this head? Alternatively, has anyone fitted a 250 sxf head (much more common around the US) and had success despite the intake cam and the valve guides being different? At this point, I would consider an entire engine at the right price. Thanks!
