best bet with the 327 is going to be find someone looking to do a numbers matching setup i guess.

as for the price of your heads, unless you got some decent flow numbers on them, i really dont see you getting 1k for them unless you find some old school guys who swear by fuelie heads. they only had 161cc intake runners, not really anything wonderful compared to the aftermarket stuff that can be had for the same price, but they are definately more bottom end torque oriented heads. im sure you could find someone, but it may be one of those things you sit on for a while if you dont sell them to your friend now.
