What would you pay for a slant six?

Okay..... I guess I'll be storing a motor and selling the intake and headers off to the best offer. Hmmm.... What would a fair price be for the intake manifold and headers as a set?

I would advertise it on your closest Craigslist and see if you get a buyer. If you do great and if you don't then split it up, then sell it by the part.
