Friend of mine has a nut and bolt restored '69 Z28 and he put NOS pistons and NOS cam in it and all the smog pump stuff too. So yeah some ppl want it exactly like it was built when new no changes no improvements ect.
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.
