I bought the set,but only installed 5 since the rest were already in. Do not need them anymore unless something bad happens to my head which i dont plan on happening. Give me offers, they are brand new and still in its original box and wrapped. They are the standard valve set. They are $239 brand new for 16 and $99 for 16 valve springs. I dont want that much so let me know. Good for someone who bends some valves since this is not all 16.
