Decent used set of 340/360 valve springs with dampers for $25 shipped

I need some nice, used 340/360 valve springs with dampers to break in my camshaft with, willing to pay $25 total OBO. I am expecting them to be worn and below factory free height and lower on seat pressure than new ones. Only reason I'm looking for them so cheap is that if I have to pay any more I might as well just buy new ones and take the dampers out.
