You just never know with these parts. I had my old D8 low compression SBF heads for sale locally for $40 bucks for 6 months or more, and not a single bite...not even a nibble. Finally, I unlisted them, wrapped them up and put them in the warehouse at work. A month later, a guy posted an want-ad online looking for a set. I told him $60 bucks and he drove straight over and picked them up.
Emissions equipment is a whole other can of worms. So many people (myself included) have removed all of that stuff, I'm sure the used (and free) market for that stuff is flooded...compared to how many people are looking for it.
