Value of BB heads

[all_about_cars]

A pair of 3946074 heads dated 7-1-69 and 7-2-69.
I bought these just as they are,I was told they were on a running engine and when it was sent to be rebuilt the heads were checked and found leake at two exhaust ports. They look pretty good but may have been welded at a lower bolt hole on both heads otherwise look good. I don’t think they are ported but not sure. They have good casting numbers and dates as well as the Winters logo. What are they worth as is?

Thanks in advance. Eddie
