I picked them up mainly for the screw-in studs ( I got them cheaper than I could have screw-ins installed) but following your advice I looked them up on a couple of sites for sale. I'm amazed at what they are selling for. I guess people who are doing restorations and want to keep original Ford parts? I think I will try to sell them and get those 'real heads'.

 

the value is dependent on the casting numbers and date code and condition . if they have not been ported, they are worth more.

if they are over the counter hi po heads from ford, they are worth the least . 66's are worth the most even though 65 and 67 heads are fr more rare.

if those heads are the real deal you need to go to church on sunday and give thanks, lol.
