I get it if you have a super duper rare numbers car but the majority of the people that drive/drove the price up on x-heads are people who aren't doing a numbers car. It's based on the perception that they are so much better.
You will have to find that buyer with a vin matching 340 block, vin matching trans who needs the x-heads or wants a spare. They are out there. My point was if the OP is going to try to sell these heads at the top of the X-head market he could wait a long time. If he wants to sell at a more realistic price then $500-700 would be a good place because it opens the market up.
