'72 Demon small block manifolds

I was going to run headers on my 360 in my '72 Demon but have been thinking about using stock manifolds instead. I would be interested in a pair of 340 manifolds if someone has a pair that they want to part with, reasonably priced of coarse. They don't have to be perfect ,as I'm not restoring the car. Let me know what's out there. Thanks.
