These springs were removed from a low mileage, genuine original aluminum head "Lightweight" comp Cobra engine that sat for decades. They will most likely be completely usable for a stock-type restoration using the original cam. Bid amount is for the 16 springs shown. The rare original flat head (not the later tulip head) hollow stem valves are not included, but I would probably consider selling those. $60 for all the springs. Email dmxf@comcast.net with interest, as I don't always check the forums daily. Thanks
