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?

the headers new are 359 un coated and the intake i think is the same... if you ebay them i would start the intake at 175 and the headers @ 200... i think StrokerScamp needs both...
