W5 Heads for sale.. how much are they worth?

sold two sets of NEW BARE w5 heads on this forum with in minutes a couple of years ago....got 1000.00 for each set...
And they ported out very nicely. Had an issue. Epoxy fixed it. But they barley went any better than an Edelbrock head.
rocker arms $300 to 500 ,shafts $200 with stands, intake $250 to $300,heads $1500.00 to $3000.00 if they are clean never hurt.
IMO, a little off. Rocker arms w/shafts and stands $1500 new, Harland, T&D, intake $150 to $200, heads $500.00 - $600 or so bare each to $3000 well ported, ready to run. I'd ask a little more for mine. Ti. valves installed.
