Anyone know what a set of '71 W-30 heads is worth? I have a set.

 

H heads if they are clean, unmolested and magnafluxed good, can bring 3000-6000 depending on condition to the "right person".

I saw a set on Ebay that looked brand new go for close to $6000, but that was 3 years ago before the floor fell out so who knows what they could bring now.
