If you're looking to sell the head and buy a flame, I guess you could ask for an estimated value of the head here:

If your head is worth somewhere around 20k or more (which it probably isn't) you could sell it and buy a simple flame with the money.
Or you can just put up a thread in the flames forum asking for a trade.
